Free Tier via Google AI Studio

Google has officially launched Gemini 3.5 Transcribe, a purpose-built speech-to-text foundation model designed to convert recorded audio and live streams into formatted text. Supporting 85+ languages, speaker diarization, word-level timestamps, and intelligent verbal clutter filtering, it brings enterprise audio transcription to developers for free.

🎧 The Two Editions: Batch vs Live Streaming

1. Gemini 3.5 Transcribe (Batch)

Processes recorded audio files up to 1 hour (or 30 minutes with speaker diarization/word timestamps). Perfect for podcast transcripts, interviews, and call records.

2. Gemini 3.5 Transcribe Live

Converts real-time streaming microphone audio into text with sub-second latency for sessions up to 10 minutes. Built for live closed-captioning and assistant interfaces.

🧹 “Smart Mode” vs “Verbatim Mode”

Feature	Smart Transcription Mode	Verbatim Transcription Mode
Verbal Clutter Filtering	Strips “ums”, “ahs”, and repetitive phrases	Preserves all filler words and pauses
Spoken Corrections	Keeps only intended word (“Friday, no Saturday” → “Saturday”)	Transcribes exact utterance literally
Speaker Diarization	Not currently supported	Supported for multi-speaker recordings
Word-Level Timestamps	Not available	Provides start & end timestamps per word

🌐 Key Technical Capabilities

85+ Language Recognition: Automatically identifies languages and handles bilingual code-switching mid-sentence.
Custom Vocabulary Prompting: Inject specialized medical, legal, or developer terminology so the model avoids phonetic misspellings.
Acoustic Noise Resilience: Tuned to isolate speech against café chatter, keyboard clicks, and heavy accents.

Within Google AI Studio, developers receive a generous free usage allowance for prototypes and personal projects. For high-volume production deployments:

Prerecorded Audio: ~$0.005 per minute of audio.
Live Audio Streams: ~$0.009 per minute of streaming audio.
