Fix misheard commands by finding the stage that fails: wake-word detection, microphone capture, speech-to-text, or intent handling. A speaker that never starts listening needs a different remedy from one that records clear audio but switches the wrong light. Test those stages in order before changing models or buying hardware.
Start with the symptom, not the hardware
Open-source voice systems are pipelines rather than single “accuracy” settings. A typical request passes through four independent stages:

| What you observe | Likely stage | First test | What a successful test tells you |
|---|---|---|---|
| No listening indicator or wake event | Wake-word detection or its enablement | Confirm the wake-word control is enabled and check the event or log | The microphone may still be fine; the detector may be disabled, using the wrong model, or not receiving frames |
| It activates, but the recording is muffled, clipped, distant, or silent | Microphone selection, audio route, placement, or capture | Record a short clip and play it back | You can hear whether the intended input is actually supplying intelligible audio |
| The recording sounds clear, but words in the transcript are wrong | Speech-to-text (STT), input configuration, or capture conditions | Inspect the transcript and compare it with the spoken phrase | A wrong transcript points downstream of wake-word detection and upstream of intent handling |
| The transcript is correct, but the wrong device or action runs | Intent, conversation rules, entity exposure, or supported phrasing | Compare the transcript with the configured intent and target entity | Microphone and STT are probably working; changing the wake-word model will not fix this failure |
Rhasspy documents separate services for audio input, wake-word detection, speech-to-text, and intent recognition. Its usage data identifies the recognized initiating word in wakewordId and the spoken transcript in text. That separation is useful even when your installation uses a different open-source assistant.

Verify that listening is enabled
First look for the device’s listening light, sound, event, or log entry. In Home Assistant’s ATOM Echo tutorial, the initial check is the device control named Use wake word. Make sure it is enabled for the satellite you are testing, then issue the exact configured wake phrase from a normal speaking distance.

If there is no listening indication, do not begin by changing speech-to-text language, intent sentences, or smart-home entities. Those components do not run until the wake-word stage hands them audio.
Try the configured model before retraining
Wake-word models differ in sensitivity, required pronunciation, and tolerance for noise. Home Assistant’s ATOM Echo troubleshooting sequence recommends adjusting the wake-word model and creating a new model when the existing one does not respond. Change one model at a time, record which model was active, and repeat the same test phrase from the same position.
Test more than one compatible speaker or satellite when practical. If another unit responds to the same phrase, the problem is local to the first unit’s input path, placement, configuration, or model deployment. If none responds, check the assistant-wide wake-word setting, service state, and model installation instead of assuming every microphone is defective.
Separate a wake-word problem from a microphone problem
A detector cannot recognize a phrase that never reaches it. Mycroft’s wake-word guidance specifically recommends checking whether the microphone is the underlying problem before blaming the wake-word model. A silent or distant recording means you should repair capture first; a clear recording that contains the wake phrase but produces no wake event justifies investigating the detector or model.
Older Rhasspy documentation includes qualitative labels such as “moderate” and “poor” in a wake-word comparison. Those descriptions are historical context, not current accuracy ratings or a controlled ranking. No comparable published misrecognition percentage is established for open-source smart speakers in the official troubleshooting material reviewed for this guide.
2. Test the microphone and audio route
Make a record-and-playback check
Use your operating system’s audio utility, the assistant’s capture test, or a platform-specific recording command to capture a short sentence. Mycroft’s audio troubleshooting documentation uses this record-and-playback method. Rhasspy provides device discovery and audio-input services that can help identify available inputs.

- Select the microphone you intend the satellite to use; do not rely on an automatic default if several inputs are connected.
- Record a sentence at the normal location and distance. Include a wake phrase only if you are testing the complete route; otherwise speak an ordinary sentence so the wake-word detector cannot mask a capture problem.
- Play the clip through headphones or another known-good output. Check for silence, severe hum, clipping, dropouts, muffled consonants, or a voice that is much quieter than expected.
- Confirm that the clip came from the selected device. A laptop microphone, webcam, Bluetooth headset, or monitor input can silently become the default after a reboot or connection change.
- Repeat once with the speaker closer to you and with nearby fans, televisions, and music paused. A large improvement indicates an acoustic or placement limitation rather than a broken STT model.
Keep the recording and the selected-device name while troubleshooting. They provide a before-and-after reference when you change a setting.

Check input discovery and channel configuration
In a Rhasspy-based setup, inspect the discovered audio devices and the configured audio-input service. Verify the expected sample source, channel count, and input device are selected. Labels vary by operating system and integration, so use the device name shown by your host rather than copying a setting intended for another board.
On a distributed satellite, confirm where audio is processed. A microphone attached to the satellite may stream frames to a Home Assistant host, while a “local” microphone setting on the host may capture the server room instead. The record-and-playback clip should identify which physical microphone is active.
Correct placement and competing sound
- Place the microphone with a clear path to the speaker’s normal position; avoid enclosing it behind a display or inside a cabinet.
- Keep the microphone away from the satellite’s own loudspeaker, rattling surfaces, and strong airflow.
- For testing, reduce television, music, kitchen appliances, and room echo. Restore normal conditions afterward to verify the fix holds.
- Speak naturally. Shouting can clip the input, while whispering may fall below the noise floor.
Home Assistant’s wake-word overview notes that speakerphones with multiple microphones and dedicated audio-processing chips can capture voice cleanly. That is a hardware category, not a guarantee: operating-system support, connection type, drivers, echo cancellation, and assistant compatibility still have to be verified.
3. Repair speech-to-text errors
Inspect what the assistant actually heard
Once the wake event occurs and the recording is intelligible, inspect the STT result. In Rhasspy’s usage format, the recognized words are exposed in the text property. Compare that text with the sentence you spoke, including names, room labels, numbers, and command verbs.
If the transcript is wrong, changing the wake-word model is the wrong lever. Retest closer to the microphone, reduce competing noise, and verify that the STT service and input device match the language and hardware you selected. A recording that is clear to you can still be difficult for an STT engine when consonants are masked by echo or when the wrong channel is being sent to the service.

Use controlled phrases to isolate the error
- Speak a short phrase with common words and no device name. This checks basic capture and language handling.
- Speak the same phrase from the usual distance and then close to the microphone. A large difference points to acoustics or gain.
- Add the room or device name. If only names fail, inspect vocabulary, entity names, pronunciation, and language configuration.
- Repeat after changing one STT setting or service. Keep the phrase and recording conditions constant so the comparison is meaningful.
Do not infer a numeric accuracy rate from a handful of successful or failed phrases. The available official material does not provide a comparable misrecognition statistic for open-source smart speakers.
4. Fix a correct transcript that triggers the wrong action
Check intent and conversation rules
A correct transcript with an incorrect result usually means the microphone and STT are functioning. Inspect the intent or conversation configuration that maps text to an action. Confirm that the recognized verb, object, room, and qualifiers match a rule your assistant supports.
For example, Home Assistant’s tutorial uses “Turn on the lights in the kitchen” as a sample spoken command. If the transcript contains those words but another light changes, inspect the entity mapping, room assignment, and action service rather than retraining the wake word.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Verify entity exposure and ambiguity
- Make sure the target device is exposed to the voice assistant and has the name you are speaking.
- Remove duplicate or near-identical names while testing. Two entities called “desk lamp” can produce an apparently random choice even with a perfect transcript.
- Check whether the assistant expects a particular phrase, such as “turn on” versus a custom synonym.
- Review area, room, and device assignments. An entity in the wrong area can satisfy a valid command but operate a different target.
- Read the intent event or log to see which rule matched, not merely which action appeared afterward.
Rhasspy treats intent recognition as its own service stage. The same diagnostic principle applies in other open-source stacks: downstream configuration cannot be repaired by microphone or wake-word changes.
5. Restart services, then preserve evidence
Mycroft documentation suggests restarting relevant services as an initial check. A restart can clear a stalled audio process, reconnect a satellite, or reload a model. Treat it as a quick diagnostic, not proof that the underlying issue is solved.
- Note the current model, microphone selection, STT service, and intent configuration.
- Save or copy recent logs and a representative failed transcript before restarting.
- Restart the affected audio, wake-word, or assistant service according to your installation’s normal procedure.
- Repeat the same wake phrase, recording, transcript, and intent tests.
- If the failure returns, compare the new logs with the saved copy instead of repeatedly rebooting.
A restart that temporarily restores listening often indicates a service, connection, or resource problem. It does not establish that the microphone, wake-word model, or intent rule is permanently correct.

6. Decide whether hardware is justified
Replace or reposition hardware only after the capture test demonstrates poor audio. A clear recording means a new microphone is unlikely to fix a downstream transcript or intent problem.
| Hardware choice | When it makes sense | Checks before purchase or replacement | What it cannot guarantee |
|---|---|---|---|
| Existing microphone, repositioned | The clip improves substantially when distance, angle, or noise changes | Stable placement, unobstructed pickup, repeatable audio test | It will not correct an unsupported STT language or bad intent rule |
| Multi-microphone speakerphone with audio-processing chips | The current clip is distant, noisy, or inconsistent and the host supports a better input | Operating-system drivers, connection type, echo cancellation, sample format, and assistant compatibility | It is not an objectively more accurate solution without a controlled test |
| M5Stack ATOM Echo | You are building or replacing a compatible Home Assistant satellite and want a documented wake-word setup | Firmware, network, Home Assistant integration, wake-word model, and the exact tutorial steps for your version | Its procedure is device-specific; it is not a universal cure for every open-source speaker |
| Exact replacement microphone, cable, or board | Only after the speaker’s make, model, connector, and board revision are known | Part number, pinout, voltage, mechanical fit, and software support | No generic replacement part can be named safely from the problem description alone |
Compatibility is system-specific. A USB speakerphone that works with one host, driver, or assistant may fail to expose the required input on another. Test the new device with the same record-and-playback procedure before changing wake-word or STT settings.
7. Understand local processing and privacy
Home Assistant documents a fully local voice path in which the microphone captures speech, local STT converts it to text, Home Assistant interprets the request, and local text-to-speech (TTS) returns the response. Its Rhasspy integration describes Rhasspy as open source and fully offline. Those are supported configuration options, not a guarantee that every installation is local.
Check the actual services configured in your system. An installation can use a local wake-word detector while sending STT or TTS to a remote service, or it can keep every stage on the Home Assistant host. Review the STT and TTS provider names, network settings, and service logs before assuming that a voice clip or transcript stays on the local network.
Rhasspy also describes a lightweight “Junior” path using a microphone and speaker connected directly to the Home Assistant host. That arrangement reduces satellite hardware, but it changes where audio is captured and may increase the importance of host placement, cable length, and local audio-driver configuration.

- Describe the failure precisely. Record whether there is no wake event, poor audio, a wrong transcript, or a wrong action.
- Confirm wake-word enablement. Check the device control, indicator, and event/log before touching STT or intents.
- Capture a clip. Select the intended input, record a normal sentence, and play it back.
- Verify the route. Use device discovery or host audio settings to ensure the clip came from the expected microphone and channel.
- Repeat under controlled conditions. Move closer, reduce noise, and compare the clip without changing several variables at once.
- Read the transcript. Use the STT result, such as Rhasspy’s
textproperty, to decide whether the failure is capture/STT or intent. - Inspect intent data. If text is correct, check exposed entities, room assignments, supported vocabulary, and the matched rule.
- Restart once and retest. Preserve logs and configuration first; a temporary improvement is evidence of a service issue, not a final diagnosis.
- Change hardware last. Consider placement or a compatible multi-microphone device only when recordings demonstrate an audio-capture limitation.
9. Common mistakes and their fixes
Changing the wake-word model to fix a bad command transcript
The wake-word detector only decides when listening begins. If the assistant wakes reliably but turns “kitchen” into another word, inspect the recording and STT result instead.
Assuming a clear response proves the microphone is good
Text-to-speech can respond normally even when the input device is intermittent or wrong. Require a recording and playback check; do not use the spoken response as evidence that the intended microphone captured your command.
Testing with several changes at once
Changing the model, microphone, STT provider, and intent sentences together removes your ability to identify the cause. Keep a one-change-at-a-time record and repeat the same phrase.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsBuying a replacement part without a model number
Connector shape, pinout, voltage, mounting, and firmware support vary. The title alone does not establish a compatible microphone, cable, speaker, or board.
Treating old qualitative comparisons as current benchmarks
Older Rhasspy wake-word descriptions are not a current, controlled product ranking. Use present-day tests on your own room, voice, hardware, and model.
10. What to record when asking for help
A useful support report lets another person locate the failing stage without guessing. Include:
- Speaker or satellite make and model, host operating system, and assistant software version.
- Whether the wake indicator or event appears.
- The selected microphone name and connection type.
- A short description of the playback quality: silent, clipped, noisy, distant, or clear.
- The exact spoken phrase and the resulting transcript.
- The recognized wake-word identifier when available, such as
wakewordId. - The intended entity, the entity actually controlled, and the matched intent or conversation rule.
- Whether the STT and TTS services are local or remote.
- What changed immediately before the failure and whether a restart altered it.
This evidence prevents a downstream intent problem from being misdiagnosed as a microphone defect and avoids unsafe hardware recommendations.

Bottom line
Diagnose in order: wake-word activation, microphone capture, transcript, then intent. Enable and test the wake-word model first; prove the audio route with a recording; inspect the actual STT text; and only then edit entities or intent rules. Restart services as a quick check, preserve logs, and consider a better microphone or a multi-microphone speakerphone only when the capture test demonstrates a hardware or placement limitation. Local processing is available in Home Assistant and Rhasspy, but verify the services your own installation actually uses.
