What is Google Cloud Speech-to-Text?
Speech-to-Text is a fully managed AI service for automatic speech recognition (ASR). The service converts audio to text and supports over 125 languages and variants. Modern deep learning models deliver high recognition accuracy, automatic punctuation adds periods and commas, and speaker recognition (diarization) identifies different speakers in conversations.
The service offers various processing modes: Synchronous recognition for short audio clips, asynchronous processing for longer files, and real-time streaming for live audio. Streaming recognition delivers results with low latency, ideal for voice assistants, live subtitles, or voice commands. Batch processing is suitable for transcribing large audio archives.
Specialized models optimize recognition for specific scenarios: Phone Call Models are trained for lower-quality phone audio, Video Models for YouTube and other media, Medical Models for medical terminology. Custom Vocabulary enables adding technical terms, product names, or industry-specific terminology for improved accuracy.
Pay-per-use billing is based on audio minutes. EU regions ensure GDPR compliance. SLA: 99.9% availability.
