Robo Translator vs Langfinity (formerly Byrdhouse)

Robo Translator is a pay-as-you-go localization service for translating text, audio, and video content into multiple languages. Built by Erudika, it uses OpenAI models for machine translation and Azure Cognitive Services for speech-to-text and text-to-speech.

You can translate documents, auto-translate and synthesize YouTube captions into multi-language audio tracks, transcribe and dub audio in one click, and localize software strings in formats like XML, JSON, plist, PHP, and properties files.

There is no monthly subscription. You top up a wallet with euros and pay per token for translation, per character for TTS, and per second for STT. New accounts receive €5 in free credits. Uploaded files are encrypted and stored on AWS for up to 30 days before deletion.

Langfinity delivers real-time voice and text translation for multilingual meetings, webinars, and live events. Pick your language once and follow the conversation as others speak in different languages, with translations shown on screen and read aloud through voice avatars.

The platform trains on company-specific terminology so industry jargon in manufacturing, technology, transportation, and other sectors translates with context instead of generic word swaps. Baseline models for popular language pairs reach over 85% accuracy, with faster voice-to-text under 300 milliseconds and voice-to-voice output in one to three seconds.

Langfinity works inside Microsoft Teams and Zoom, and supports in-person events through QR codes that let attendees get live translation on their phones. Organizations use it for global team meetings, church services, conferences, and client calls where hiring human interpreters would be slow and costly.
