Accurate AI transcripts start before you press Record. Pair the recorder correctly, select the real microphone and spoken language, place the microphone close to the conversation, prevent people from talking over one another, and keep the app connected until the upload begins. Before generating a summary, add names and jargon to Custom Vocabulary and choose a template that explicitly asks for decisions and action items. Finally, check names, numbers, speaker labels, decisions and tasks against the audio.
No recorder has one guaranteed accuracy percentage for every room, language or group. Microphone distance, background noise, overlapping speech and configuration determine what the system can recognize. The workflow below is designed to remove those avoidable sources of error.

What determines transcript accuracy
An AI recorder can only transcribe the audio it receives. A high-quality model cannot recover a quiet sentence that was masked by a loud air conditioner, a speaker sitting several metres away or two people speaking at the same time. Treat the process as a chain: capture, transfer, transcription settings, summary generation and human review. A failure in any link can look like a “bad AI” result.

Prepare the recorder and app before the meeting
Dedicated recorder: pair it first
Charge or power the recorder, install or open its companion app, sign in and grant microphone or Bluetooth permissions when requested. For a Notta Memo or Memo Pro, the documented path is Settings → Smart devices → Connect. Turn on the recorder and complete Bluetooth pairing in that screen. A successful pairing should be confirmed before the meeting, not discovered when an important conversation has already started.
Phone or computer: choose and test the input
If you are recording with a phone or computer, open the recorder or transcription app and select the microphone you intend to use. A laptop may have several inputs: its built-in microphone, a headset and an external USB microphone. Select the one physically positioned for the meeting. Otter’s setup guidance recommends testing the selected microphone before an event. Record a short sample, play it back and listen for a clear voice, excessive room noise or a channel that is not recording at all.
Run a short end-to-end test
- Start a test recording with the same room layout and microphone position you will use for the real session.
- Have one or two people speak at normal meeting volume, including any names or technical terms likely to appear later.
- Stop the recording rather than leaving it paused, wait for the upload or processing indicator, and open the resulting transcript.
- Confirm that audio playback, text generation and the intended account or workspace all work before the event begins.
This test catches permission, pairing, input-selection and connectivity problems while they are still easy to fix.

Place the microphone for clean audio
For a group around a table
Place the recorder near the centre of the table, keep it still and avoid covering its microphones with papers, a hand or a case. Central placement reduces the distance to the quietest participant and gives the recognizer a more even signal. Keep the device away from a laptop fan, speaker grille, keyboard and cups that may be moved during the meeting.
For one main speaker
Put the microphone within about 3 feet (1 metre) of the target speaker, the distance recommended in Otter’s help guidance. Closer is generally better when the room is noisy, provided the microphone is not so close that handling noise or breath overwhelms the voice. If the speaker moves, move the recorder or use a microphone that follows the speaker rather than leaving the device at the far end of the room.
Control the room
- Choose the quietest available room and close doors and windows when outside noise is intrusive.
- Reduce background noise from fans, televisions, projectors and nearby conversations.
- Ask participants not to speak over one another. Overlapping speech is a primary cause of missing words and incorrect speaker attribution.
- Keep the recorder stationary. Sliding it across a table or handling it during speech adds noise that competes with voices.
When a computer is the recording device, an external USB microphone can improve capture quality compared with a distant built-in microphone. Test the USB input in the app before relying on it, because connecting hardware does not always change the selected input automatically.

End the recording and protect the upload
Use Stop, not Pause, when the session is finished
Otter’s help guidance specifically recommends using Stop instead of Pause whenever possible. Stop closes the recording cleanly and starts the handoff to processing. Pause is useful for a temporary break, but a paused session is easier to forget or leave in an ambiguous state.
Keep the transfer alive
After stopping, keep the recorder, app or browser connected until the upload completes and processing starts. Do not force-quit the app, close the browser tab, disconnect Bluetooth or allow the device to sleep during the transfer. If the connection drops, reopen the app and look for a pending or locally stored recording before starting a second copy; duplicate recordings make later review harder.
Confirm that processing has begun
Look for a completed upload, a processing status or a transcript entry before leaving the meeting setup. If the recording remains local, reconnect the device or network and allow the transfer to finish. A perfect recording that never reaches the transcription service cannot produce a transcript or summary.
Set language and vocabulary controls before transcribing
Select the language that is actually spoken
Choose the conversation’s primary language in the transcription settings rather than leaving an automatic default that may be wrong. PLAUD documents support for more than 112 transcription languages and notes that manually selecting a less common language can improve results. If a meeting genuinely switches languages, check whether your workflow supports the required language combination; do not assume that a single-language setting will identify every switch correctly.
Add names, acronyms and jargon to Custom Vocabulary
Before processing, enter the words the recognizer is most likely to mishear: participant names, company or product names, acronyms, specialist terminology, medications, locations and project codes. PLAUD Support describes Custom Vocabulary as a practical setup check. Use the spelling and capitalization you want displayed in the final transcript. Add likely variants only when they represent distinct spoken terms; an oversized list can make it harder to notice a genuine new word.
Decide how speakers will be identified
Speaker labels are useful for meetings with several participants, but they depend on distinguishable voices and clean turn-taking. In PLAUD AutoFlow, speaker labeling is one of the settings that can be configured alongside the source, language, template, duration and model. If the transcript assigns a line to the wrong person, preserve the spoken content first and correct the attribution during review. A label is a claim about who spoke, not a substitute for listening to the audio.

Generate a summary that captures decisions and action items
Use an automatic workflow when the recording meets its threshold
PLAUD’s AutoFlow automatic processing requires more than 200 words, which is roughly five minutes of speech. Short sound checks or very brief calls may not meet that threshold and may need manual processing. In AutoFlow, set the recording source, duration, language, summary template, speaker-label option and model before starting the job.
Choose Auto or Custom generation deliberately
PLAUD offers Auto generation and Custom generation. Auto is convenient when a general summary is sufficient. Custom generation lets you choose the output language and a summary template, which is preferable when the reader needs a predictable structure. Select a template that asks for the following fields rather than simply requesting “summarize”:
- Decisions: What was agreed, approved or rejected?
- Action items: What must be done next?
- Owner: Who is responsible for each task?
- Due date: When is the task expected, if a date was spoken?
- Open questions: What remains unresolved?
- Risks or dependencies: What could block the next step?
A template cannot invent a missing owner or deadline. If the meeting never assigned one, a reliable summary should say that the owner or date was not specified instead of guessing.
Match the summary language to the audience
Set the output language independently when the tool allows it. A team may speak one language but need an executive summary in another. Check names, acronyms and numbers especially carefully after translation or language conversion.
Review and repair the transcript
Do not treat the first generated text as a meeting record. Review the transcript while the audio and context are fresh. Start with the details that can change a decision or create an obligation.
- Play the opening and closing minutes. Confirm the meeting title, date, participants and final commitments.
- Search for names and numbers. Verify people, product codes, prices, percentages, quantities, dates and times against the audio.
- Check speaker labels. Listen to every line that assigns an approval, refusal or task to a particular person.
- Check decisions. Compare each decision in the summary with the exact wording in the transcript and recording.
- Check action items. Confirm the task, owner and due date. Mark any field that was not stated rather than filling it from memory.
- Inspect low-confidence passages. Room noise, crosstalk, accents and uncommon terms deserve a slower replay.
If jargon or a name is wrong, add the correct form to Custom Vocabulary and reprocess the recording. If many words are wrong, verify the selected language and microphone source before trying another summary template. Reprocessing the same flawed audio cannot restore speech that was never captured clearly, so improve the capture setup for the next session.

Fix common failures
Missing words or long gaps
- Replay the audio to determine whether the words were recorded at all.
- If the audio is quiet, move the microphone closer or place it centrally next time; a target speaker should be within about 3 feet (1 metre) where practical.
- Reduce fans, traffic, keyboard noise and other background sound.
- Check that the selected microphone was the one physically in use.
Two speakers merged into one passage
Overlapping speech is difficult for both transcription and speaker labeling. Ask participants to take turns, use a central microphone and keep the device stationary. During review, separate the passage only when the audio makes the change of speaker clear; do not infer a speaker from the subject of a sentence.
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 errorsWrong language or badly spelled technical terms
Set the language manually, especially for a less common language, and add names, acronyms and jargon to Custom Vocabulary before reprocessing. If the meeting contains frequent language switching, split the recording into language-consistent segments when your workflow permits it.
The recording is not visible after stopping
Check whether the app or browser is still uploading. Reconnect the recorder or network and keep the session open until processing starts. Avoid creating a second recording while the first transfer is pending, and do not force-quit an app that is still transferring data.
The summary omits a decision or task
Read the transcript around the relevant discussion and confirm that the decision was actually spoken. Then use a custom template that requests decisions, action items, owners and dates. If the transcript itself is wrong, repair the vocabulary, language or speaker attribution first and regenerate the summary.
Choose a setup that fits your meeting
The best setup is the one you can test, place close enough to speakers and keep connected through upload. The documented capabilities below distinguish the main approaches without promising a universal accuracy advantage.

A repeatable meeting procedure
Use this short procedure when you need the same result every time:
- Before participants arrive: Pair the recorder or select the computer microphone, grant permissions and record a short test.
- Place the device: Put it centrally for a group or within about 3 feet (1 metre) of the main speaker. Remove nearby noise sources.
- Set controls: Choose the spoken language, load Custom Vocabulary and select speaker labeling or the appropriate summary template.
- Record: Keep the device still and ask people to avoid talking over one another.
- Finish: Press Stop, not Pause, and leave the app, browser or recorder connected until upload and processing begin.
- Review: Check names, numbers, labels, decisions and action items against the audio.
- Repair: Correct vocabulary or language settings and reprocess when the audio is clear but the text is wrong. For genuinely unclear audio, annotate the uncertainty and improve microphone placement next time.
What to expect from automatic summaries
An automatic summary is an extraction of the transcript, not an independent record of everything that happened. It can organize an explicit decision or task, but it cannot reliably supply an owner, date or rationale that participants never stated. For consequential meetings, retain the reviewed transcript or the relevant audio alongside the summary so readers can verify the wording.
Short recordings may fall below PLAUD AutoFlow’s more-than-200-word threshold, and a summary generated from incomplete upload data will be incomplete regardless of template. Treat the processing status and the review step as part of the recording workflow, not as optional administration.
