    Project mention: Ask HN: Real-time speech-to-speech translation | news.ycombinator.com | 2024-10-24

    Has anyone had any luck with an offline, free, open-source real-time speech-to-speech translation app on under-powered devices (i.e., older smart phones)?

    * https://github.com/ictnlp/StreamSpeech

    * https://github.com/k2-fsa/sherpa-onnx

    * https://github.com/openai/whisper

    I'm looking for a simple app that can listen for English, translate into Korean (and other languages), then perform speech synthesis on the translation. Basically, a Babelfish that doesn't stick in the ear. Although real-time would be great, a 3- to 5-second delay is manageable.

    RTranslator is awkward (couldn't get it to perform speech-to-speech using a single phone). 3PO sprouts errors like dandelions and requires an online connection.

    Any suggestions?
