Strengths

Pros

  • Model weights and inference code are public
  • Can run locally for data control
  • Supports hosted API and enterprise deployment paths
Considerations

Cons

  • Current public model supports English only
  • Local inference requires substantial GPU memory
  • Voice cloning creates impersonation and consent risks
Considerations

Limitations

Miso TTS is a speech-generation model and can be misused for impersonation or deceptive audio. Deployers must obtain voice rights, maintain watermarking and abuse controls, disclose synthetic content when required, and validate hardware, latency, quality, and license obligations.
