transcription
Voicebox Tool
A local-first voice stack bundling voice cloning, TTS, Whisper transcription and dictation, a refinement model, a REST API, and a built-in MCP server so an agent can speak, transcribe, and manage voice profiles without cloud calls.
OpenAI Whisper Tool
OpenAI's open-source speech-recognition model family and the reference baseline Apple's SpeechAnalyzer was measured against - freely runnable locally in sizes from tiny to large for transcription and translation.
Gemini 3.5 Transcribe Tool
Google's new transcription model, shipped as two endpoints: a bidirectional streaming version for live voice agents and a batch version with speaker attribution and word-level timestamps. Handles 85+ languages with mid-stream language switching, cleans filler and self-corrections automatically, and can make function calls to other Gemini models. Try it in AI Studio.
Apple SpeechAnalyzer Tool
Apple's on-device speech-to-text API that cut errors roughly fourfold over the legacy recognizer and beat Whisper Small using about a third of the compute - private, local transcription with no cloud round-trip.
