Behind TransTalk: How Google Speech-to-Text and Neural TTS Power Real-Time Call Translation

A deep dive into the technology stack behind TransTalk's sub-second translation pipeline and 150+ language support.

What is TransTalk?

TransTalk is an AI-powered mobile app that provides real-time call recording and translation. It works on regular phone calls and within apps like WhatsApp, WeChat, and Telegram. Speak in your language, and TransTalk translates both sides of the conversation so each person hears it in their own language — instantly.

How does real-time call translation work?

TransTalk uses a three-step pipeline: Speech-to-Text (Google-grade recognition converts spoken words to text), Neural Machine Translation (AI translates the text to your target language), and Text-to-Speech (natural-sounding voice reads the translation aloud). This entire process happens in under one second, making conversations feel natural and seamless.

Which languages are supported?

TransTalk supports over 150 languages and dialects, including Spanish, Mandarin Chinese, Arabic, Hindi, French, Portuguese, Japanese, Korean, German, Italian, Russian, Vietnamese, Thai, and many more. Powered by Google Speech-to-Text and Google TTS, our engine handles regional accents with impressive accuracy.

Does it work with WhatsApp and other apps?

Yes! TransTalk works with WhatsApp, WeChat, Telegram, Zoom, FaceTime, and more. For video and voice calls on these platforms, TransTalk provides bilingual subtitles that appear in real time on both screens. Simply share an invite link, and you're ready to go — no complicated setup required.

Is my call data private and secure?

Absolutely. We take privacy seriously: all call audio is encrypted in transit using TLS, voice data is processed securely and not stored longer than necessary, and we are fully GDPR-compliant. Your conversations are your own — TransTalk never shares, sells, or mines your call data.

Can I use my own phone number?

Yes! TransTalk includes built-in phone number management. You can use your existing phone number for calls, or obtain new numbers from different countries for your business. All through the same app — no extra hardware or carrier changes needed.

Is there a free trial?

Yes! You can start for free with a generous trial that lets you test all core features. Make translated calls, try WhatsApp translation, and explore the app at your own pace. No credit card required to get started.

Which platforms is TransTalk available on?
