Palabra.ai
Palabra.ai provides live speech translation for calls, events and broadcasts, alongside speech-to-text and text-to-speech services for developers. Its official product page separates ready-made translation apps from the API used to embed speech processing in another product.
Calls, events and broadcasts
The ready-made tools provide two-way translated speech and live captions. Palabra lists Zoom, Google Meet and Microsoft Teams as supported meeting tools. For in-person events, attendees can scan a QR code, choose a language, and listen or read captions on their own devices. This makes the audience access method different from an individual translated meeting.
Broadcast workflows accept SRT and RTMP streams. The publisher also names OBS, vMix and YouTube among its supported broadcast workflows. Teams can use custom glossaries for domain vocabulary, choose prerecorded voices, or use voice cloning. Speaker diarization identifies different speakers in supported workflows.
Developer integration
The streaming API covers speech recognition, translation and synthesized speech, with WebRTC and WebSocket connections. Palabra lists automatic language detection across more than 60 languages, instant voice cloning and custom glossaries among its API features. Its standalone speech recognition and speech synthesis services also support applications such as voice agents.
For enterprise deployments, the company offers regional private servers and describes private-cloud or on-premises options. Palabra states that it encrypts conversations and does not store conversation data. These are the publisher's stated operating policies; organizations with specific requirements can use the offered sales discussion to establish their deployment terms.
Pricing and operational limits
The pricing page lists API speech synthesis at $0.03 per 1,000 characters, speech recognition at $0.002 per audio minute, and speech-to-speech translation at $0.04 per minute. It advertises $50 in sign-up credits and up to ten concurrent API sessions per account.
Meeting, event and broadcasting plans use separate capacity and feature tiers. For example, event tiers differ in stage counts and cloned voices, while broadcast tiers differ in simultaneous output languages. Confirm the billing period and the tier that matches your setup before booking an event.
Palabra advertises sub-second translation latency, but its headline 35 ms text-to-speech figure is specifically time to first audio excluding network latency. Emotion transfer is marked as coming soon. Those qualifications matter when comparing the live service with a complete end-to-end conversation experience.
