Unbabel Talk is a speech-to-speech translation application that provides human certified translations for voice instant messaging (IM) in multilingual scenarios. By combining Unbabel’s translation pipeline with state-of-the-art automatic speech recognition (ASR) and text-to-speech (TTS) models, Unbabel Talk can be used to send a voice message in a language of choice through popular messaging platforms. The app further ensures that translations have high quality, either by certifying them through Unbabel’s own quality estimation (QE) tool and/or through Unbabel’s community of translators. There are two versions of the app. On version 1, the app synthesizes audio that can be delivered with male or female standard voices. Version 2 has features that are currently being developed, such as voice morphing and transcription correction through Unbabel’s community.
