Shared compatibility

  • Python · speech-to-speech: Python runtime · StreamSpeech: Python runtime

Choose speech-to-speech if…

  • License: speech-to-speech is Apache-2.0, StreamSpeech is MIT.
  • Pricing: Free and open-source software under the Apache-2.0 license, with possible premium services based on usage or special features not covered in this repository..
  • Requirements: Min 4 GB RAM; Requires Docker; Docker setup may require additional resources and the installation of the NVIDIA Container Toolkit for non-standard setups..
  • Tags unique to speech-to-speech: ai, assistant, language-model, machine-learning.
  • speech-to-speech ships Docker support for self-hosted deployment.
  • When you need to leverage open-source components for real-time speech processing in your projects, as speech-to-speech provides an integrated solution with Parakeet TDT for STT.

When NOT to use speech-to-speech

  • When the need arises for a voice agent solution that exclusively utilizes proprietary models or services, as speech-to-speech depends fully on open-source components.
  • For projects aiming to run exclusively under macOS without cross-platform capabilities, despite automatic dependency resolution between different platforms.

Choose StreamSpeech if…

  • License: StreamSpeech is MIT, speech-to-speech is Apache-2.0.
  • Tags unique to StreamSpeech: all-in-one, asr, machine-translation, speech-recognition.
  • Use StreamSpeech when you need a compact model that can handle speech recognition, translation, and synthesis simultaneously without relying on online services.

When NOT to use StreamSpeech

  • Do not use StreamSpeech in scenarios where online connectivity is required due to its offline processing nature.
  • Avoid it when the target application demands autoregressive models, as StreamSpeech focuses on non-autoregressive techniques which might offer different performance characteristics.
