Google unveils Gemini 3.5 Transcribe, its most accurate speech-to-text model yet, with features like real-time streaming and multi-speaker attribution.
Google has introduced Gemini 3.5 Transcribe, a new addition to its Gemini AI model family, aiming to redefine speech-to-text transcription capabilities. The announcement, made on August 26, highlights improvements in accuracy, real-time capabilities, and support for over 85 languages. Developers and enterprises can now integrate this advanced model via the Gemini API and Enterprise Agent Platform.
Gemini 3.5 Transcribe is designed to handle real-world challenges like background noise, speaker disfluencies, and complex vocabulary. The model boasts a Word Error Rate (WER) of just 4.0% for live streaming and 2.6% for pre-recorded audio, significantly outperforming its predecessor, Chirp 3. Improvements in latency have also been noted, with time-to-final transcription reportedly 70% faster. These metrics, as measured by Artificial Analysis, position Gemini 3.5 as one of the most precise transcription tools on the market.
Google has introduced two APIs for the model:
- Real-time Streaming: Designed for interactive apps, this API offers bidirectional streaming with sub-second latency, ideal for live captioning and voice assistants.
- Pre-recorded Audio Processing: This API allows transcription of recorded meetings, call logs, and more, complete with speaker attribution and word-level timestamps.
The model also supports advanced features such as custom vocabularies for industry-specific jargon, seamless handling of interruptions and corrections, and multi-speaker attribution for up to three speakers. Additionally, it integrates with other Gemini models to perform tasks like image generation and file analysis via voice commands.
Consumer and Developer Adoption
Gemini 3.5 Transcribe is already available across major Google products. Android users can use the Rambler feature on Gboard for polished voice-to-text transcription, while macOS users can leverage the Gemini app for dictation and workflow automation. Developers can access the model through Google AI Studio and the Antigravity platform.
Since the broader Gemini 3.5 family launched in May 2026, Google has steadily expanded its portfolio of AI-powered tools. Earlier iterations, such as Gemini 3.5 Live Translate, focused on real-time speech-to-speech translation in over 70 languages. The launch of Transcribe appears to complement these efforts, emphasizing transcription accuracy and intelligent voice interactions.
Enterprise Use Cases
Enterprises are already exploring use cases for Gemini 3.5 Transcribe in industries like healthcare, customer service, and media. Companies such as Vivo and Lingopal have praised the model’s low latency and multilingual capabilities, which are critical for global operations. Developer platforms including Agora, LiveKit, and Vercel offer integration options, enabling businesses to create voice-driven interfaces without the need for complex backend infrastructure.
What’s Next?
Google plans to roll out Gemini 3.5 Transcribe to Chrome in the coming months, allowing users to dictate directly into web fields. The model’s ability to automatically clean up filler words and adapt to context could make it a go-to tool for professionals who rely on voice-driven workflows. It is currently in public preview for developers and enterprises, with general availability expected later this year.
With its advanced capabilities and seamless integration across Google’s ecosystem, Gemini 3.5 Transcribe is set to push the envelope for speech-to-text technologies, making voice interactions more accurate and intuitive than ever before.
