What users say

On the record, from teams already running it

We used Palabra during a recent metaverse event hosted on Walcon Virtual, and it added great value to the experience. The live translation helped us reach a broader audience and made the event more accessible.
BV Brian VertoneGeneral Manager, Walcon Virtual
The translated speech is more concise and coherent, making it easier to either read or listen to. Palabra is able to detect language change and yield corresponding interpretation — good for a fireside discussion.

What's inside

One pipeline, seven ways to use it

S2S

Speech‑to‑speech translation

Live two‑way translation across 60+ languages, with automatic language detection mid‑conversation.

TTS

Text‑to‑speech

35ms time‑to‑first‑audio (P90), streamed — the company's fastest‑TTS claim is verified by the COVAL benchmark.

STT

Speech‑to‑text

Real‑time transcription with speaker diarization for multi‑speaker sessions.

VC

Instant voice cloning

Clones the speaker's own voice automatically, so translated audio still sounds like them.

GL

Custom glossaries

Lock in business‑ or industry‑specific terminology so it translates consistently every time.

CC

Live captions

Translated captions alongside or instead of audio, for hybrid audiences.

API

Developer API & SDKs

WebRTC/WebSocket streaming to embed the full ASR → translation → TTS pipeline in your own product — the same engine behind everything above.

Deployment

Teelacodes verdict

Where it earns the "fastest" claim — and where the bill adds up

Strong pick for teams that live in video calls and streams across languages; read the per‑hour math before committing to events.

4.4
/5 — editor's take

Pros

  • Own proprietary LLM, not a third‑party translation API — more room to tune quality
  • Sub‑second latency with an independently verified TTS speed benchmark
  • Voice cloning is automatic, not a paid add‑on
  • Drops straight into Zoom, Meet, Teams, OBS and vMix with no plugin
  • Zero conversation data retention, plus ISO 27001 / SOC 2 / GDPR / HIPAA coverage

Cons

  • Emotion transfer is still listed as "coming soon," not shipped yet
  • In‑person event and livestream plans bill per hour and scale fast for large productions
  • Business‑tier pricing needs a sales call — no self‑serve number on the page
  • Full value depends on network conditions; latency figures are best‑case

FAQ

Questions before you start

What is Palabra.ai, exactly?

A real‑time AI speech translation platform: automatic speech recognition, translation and natural text‑to‑speech in one pipeline, for live video calls, in‑person events, streams and developer integrations.

Is the translation really under a second?

Palabra states sub‑second end‑to‑end latency with a 35ms time‑to‑first‑audio (P90) for its TTS, independently referenced against the COVAL benchmark. Real‑world latency still depends on your network.

Does the translated voice sound natural, or robotic?

It auto‑clones the original speaker's voice, so output keeps their vocal identity rather than switching to a generic TTS voice. Emotion transfer is listed as a coming‑soon feature, not shipped yet.

What platforms does it work with?

Video calls: Zoom, Google Meet, Microsoft Teams, no plugin required. Streaming: OBS, vMix, YouTube, Vimeo, Castr via SRT/RTMP. Developers: a WebRTC/WebSocket API and SDKs for custom integrations.

What happens to my conversation data?

Palabra states it does not store conversation data and encrypts everything in transit, with ISO 27001, SOC 2 Type II and GDPR attestations, plus HIPAA‑ready deployment options for enterprise.

How do I start, and does it cost anything upfront?

The end‑user app has a free trial with easy cancellation and no card required. Developers get $50 in free API credits on sign‑up. Paid plans only kick in once you outgrow the free tier.
