Google has launched a new text-to-speech API built on the Gemini 3.1 Flash model, introducing a notably different interface from traditional TTS systems. Rather than selecting from a dropdown of preset voices, developers describe the voice they want in natural language — tone, pacing, emotional register, regional accent — and the model interprets those instructions. Multi-speaker dialogue is supported in a single API call, with different voice characteristics per speaker. The API covers 70+ languages with high fidelity across all of them, including real-time streaming output for low-latency use cases. Inline audio tags in the prompt let developers mark specific phrases for different treatment — whispering a secret, emphasizing a warning, letting a character laugh mid-sentence. This level of fine-grained control without manual audio editing is new for a production-grade API. Priced competitively with a free tier through the Gemini API and enterprise availability via Vertex AI. Positioned directly against ElevenLabs, Deepgram, and Cartesia. The conversational direction interface in particular is a departure from the incumbent approach and could significantly lower the barrier for developers building audio-first products.
Reviewer scorecard
“I cloned my voice in 30 seconds and now my AI narrates my YouTube videos while I sleep. The quality is indistinguishable from me. Terrifyingly good.”
“For audiobook production, podcast automation, and multilingual content this is immediately useful. The inline audio tags for within-sentence expression changes are exactly what creators have been asking for — no more splitting scripts into dozens of segments to get natural emotional delivery.”
“The voice quality is legitimately best-in-class. My only concern is the ethical implications, but as a product, it simply works.”
“Natural language voice direction sounds great in demos but may be unpredictable in production — you can't guarantee the same voice characteristics across API calls without exact prompt pinning. ElevenLabs and Cartesia offer voice IDs for reproducibility. Also, Google's track record with deprecating APIs makes long-term commitment to this TTS service uncertain.”
“Voice becomes an API. Every app will have a voice layer within 18 months. ElevenLabs is the Stripe of audio AI — the infrastructure play.”
“Voice as a fully programmable medium — described in natural language rather than parameterized — is a paradigm shift. Combined with real-time streaming, this makes high-quality audio generation available to any developer, not just audio specialists. The long-term trajectory is voice as just another output modality in any AI product.”
“The natural language voice direction is legitimately new — I've been building with ElevenLabs and the voice selection process has always been tedious trial-and-error. Being able to say 'calm, slightly British, measured pace' and get that is a real quality-of-life improvement. Multi-speaker in a single call is also a huge convenience for dialogue-heavy apps.”
