Google Cloud Speech-to-Text
What Google Cloud Speech-to-Text is
Google Cloud Speech-to-Text converts audio into text and provides APIs for adding speech recognition to applications. Recognition can run synchronously, asynchronously, or as a stream for post-processing, periodic updates, or real-time results. The product page lists support for more than 85 languages and variants. Users can provide model-adaptation hints for specialized terminology, uncommon words, and phrases; speaker diarization can attribute utterances to speakers. The service also supports multichannel audio and says it can process noisy audio without extra noise cancellation. Specialized models target voice control, phone calls, and video transcription. API v2 includes data residency, audit logging, and customer-managed encryption keys. An on-premises edition runs in customers’ private data centers and is offered through a sales contact. Developer access includes REST and RPC APIs, client libraries, and command-line quickstarts. Costs depend on audio duration, channel count, model, batch method, and API version, with each channel billed separately. Some plans include 60 free minutes per month; listed plan rates vary by recognition mode and version.
