Speech-to-speech and speech-to-text translator trusted by global teams

Brian Vertone
General Manager at Walcon Virtual

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

Meg Hsieh
Sales Manager at GIS Group

“We like Palabra interpretation as either in Chinese or English, the translated speech is more concise and coherent, making it easier to either read or listen to. Also, Palabra is able to detect language change and yield corresponding interpretation. This is good if we use it during a fireside discussion.

Dhaou Amor
Head of Business Development at Cardoo

“We used Palabra translator in our call center for partner calls in European languages like Spanish, French, and German, especially when the other side didn’t speak English. It helped us handle difficult language pairs and made rental deposit confirmation calls faster and more successful. The glossary feature was a big plus for our jargon, keeping translations accurate and natural.

Saptarshi Chakraborty
Co-Founder & Product Owner at EventLabs

“At EventLabs, we rely on Palabra for real-time translation during conferences and live events. Among all the solutions we’ve tested, Palabra stands out with the highest translation quality and the lowest latency by a significant margin. The platform’s speaker autodetection, differentiating between male and female voices and adapting translations in real time, has noticeably improved the listener experience. For us, Palabra is setting the benchmark for event translation technology.

Common questions about live speech translation with Palabra.ai

What is Palabra?

Palabra is an advanced AI translator tool designed for real-time speech translation. It provides seamless AI translation and interpretation services for video calls, live events, streaming, and can be integrated via API. Think of it as an instant translator designed for dynamic communication needs.

What platforms and apps does Palabra work with?

Palabra is designed for wide compatibility, making it one of the best translation apps for various scenarios.

  • Desktop App (Windows & Mac): This voice translation app works with major video conferencing tools like Google Meet, Zoom, Microsoft Teams, Slack, Discord, WhatsApp, and other VoIP services. Mac users might find it the best translation app for calls handled through their computer.
  • Broadcaster: Our no-code solution integrates with modern streaming platforms like OBS, vMix, YouTube, Vimeo, Castr, Cloudflare, using protocols like SRT and RTMP.
  • API/SDKs: Allows integration into virtually any product or service needing real-time voice capabilities.
How accurate is Palabra's translation? Is it comparable to a human interpreter?

Palabra achieves human-like accuracy. Our real-time speech translation, powered by our own advanced LLM, is designed to be as accurate as a professional interpreter. We strive to be the best translator available by delivering high-quality, reliable results, often exceeding the capabilities of standard translation devices in real-time scenarios. It helps bridge the gap in the interpreter vs translator discussion for live interactions, offering the best translate quality via AI.​

Is the real-time speech translation truly instant?

Yes. Palabra provides simultaneous two-way automatic translation with less than one second of latency. This ensures conversations flow smoothly, making it a true instant translator.

Does the translated voice sound natural?

Absolutely. The translated voice is designed to sound natural. Palabra automatically selects a voice similar to the original speaker and features speaker's voice auto-cloning. This creates a more natural dubbed AI effect than robotic voices. It acts like a sophisticated talking translator app for verbal translation or a voice interpreter app, aiming to preserve vocal identity. Emotion duplication is also a planned feature.

Can I get translated captions instead of audio?

Yes, Palabra supports real-time speech-to-text translation. Your audience can choose to listen to or read the translation, giving them flexibility based on their needs and abilities.

Can I integrate Palabra's AI translation into my own application or service?

Yes. We provide fast, flexible, and deeply customizable APIs and SDKs. This allows developers to integrate Palabra's powerful AI translation pipeline (including ASR, Translation, and TTS) into their own products, creating a seamless experience for their users.

What makes Palabra different from other translation apps or devices?

Palabra stands out because it's built on our own proprietary Large Language Model (LLM). This gives us full control over performance, quality, and flexibility, unlike services relying solely on third-party models. Key advantages of our AI speech translator include:

  • Unmatched accuracy and speed.
  • Ability to add custom languages.
  • Glossary management for specific business needs.
  • Speaker's voice auto-cloning out of the box.
  • Deployment of proprietary servers in your region for minimal delay.
  • Complete data security and privacy.

These features make it one of the best translating apps and a strong contender for the best language translator app for professional use cases, going beyond typical translation devices.

Is Palabra secure? What happens to my conversation data?

Security is a top priority. All conversations processed by Palabra are encrypted. Critically, we do not store any conversation data, ensuring total confidentiality and privacy for your communications. For enterprise customers with advanced security needs, Palabra also supports deployments in private clouds or on-premises environments.

What are the main use cases for Palabra?

Palabra is versatile:

  • Events & Conferences: For in-person, virtual, or hybrid events of any size.
  • Video calls: Ideal for international teams or client calls.
  • Sales & Customer Support: Communicate with customers in their native language to improve satisfaction and conversions.
  • Streaming: Make gaming streams, live sports, or webinars globally accessible.
  • Enterprise Integrations: Enhance services like dating apps, social commerce, gambling platforms, or video streaming services with real-time speech translation.
