Explore how to build speech-to-text applications using Gemini 3.5 Transcribe models and the Google GenAI SDK. Learn the two primary implementation patterns: synchronous batch processing for pre-recorded audio and low-latency streaming over WebSockets via the Live API. From there, explore essential configuration knobs, such as word-level timestamps, multilingual language codes, speaker diarization, and custom vocabulary biasing to produce highly accurate, production-ready transcriptions.
