Google Cloud Speech-to-Text
What it is
Google Cloud Speech-to-Text converts audio into text and exposes APIs for adding speech recognition to applications. It supports synchronous, asynchronous, and streaming recognition for post-processing, periodic workloads, or real-time results, with 85+ languages and variants listed. Model adaptation lets users provide hints for specialized terms, rare words, and phrases. Speaker diarization identifies which speaker produced each utterance, while multichannel recognition and noisy-audio handling support varied recordings. Google offers models tuned for voice control, phone calls, and video transcription. Speech-to-Text API v2 includes data residency, audit logging, and customer-managed encryption keys. Speech-to-Text On-Prem runs in customers’ private data centers through a sales contact. REST and RPC APIs, client libraries, and command-line quickstarts support developer access. Export formats include VTT and SRT. Billing depends on audio duration, channels, model, batch method, and API version, with each channel billed separately. Listed plans include $0.00 dynamic batch processing and 60 free minutes per month on some V1 plans; other listed rates include $0.016 / 1 minute and $0.08 per month plans.
