Watch a live demo of Telnyx’s speech-to-text API transcribing a phone call using the voice API. Real-time voice insights in action.
Real-time transcription is becoming a must-have for applications that handle voice. Whether you're building support tools, voice analytics, or AI training pipelines, capturing what’s said on a phone call —in the moment— unlocks huge value.
With the speech recognition market expected to exceed $50 billion by 2030, now’s the time to add voice intelligence to your stack.
A speech-to-text API lets you convert spoken language into readable, structured text. Paired with the Telnyx Voice API, you can place and receive phone calls, and transcribe them live as they happen without needing deep telecom knowledge.
