Cloned the GitHub repo for easier viewing and embedding the above table as once requested by @reach-vb: https://github.com/Vaibhavs10/open-tts-tracker/issues/30#issuecomment-1946367525

Legend

for the above TTS capability table

• Processor ⚡ - Inference done by
  • CPU (CPUs = multithreaded) - All models can be run on CPU, so real-time factor should be below 2.0 to qualify for CPU tag, though some more leeway can be given if it supports audio streaming
  • CUDA by NVIDIA™
  • ROCm by AMD™
• Phonetic alphabet 🔤 - Phonetic transcription that allows to control pronunciation of words before inference
  • IPA - International Phonetic Alphabet
  • ARPAbet - American English focused phonetics
• Insta-clone 👥 - Zero-shot model for quick voice cloning
• Emotion control 🎭 - Able to force an emotional state of speaker
  • 🎭 <# emotions>
    • 😡 anger
    • 😃 happiness
    • 😭 sadness
    • 😯 surprise
    • 🤫 whispering
    • 😊 friendlyness
  • strict insta-clone switch 🎭👥 - cloned on sample with specific emotion; may sound different than normal speaking voice; no ability to go in-between states
  • strict control through prompt 🎭📖 - prompt input parameter
• Prompting 📖 - Also a side effect of narrator based datasets and a way to affect the emotional state
  • 📖 - Prompt as a separate input parameter
  • 🗣📖 - The prompt itself is also spoken by TTS; ElevenLabs docs
• Streaming support 🌊 - Can playback audio while it is still being generated
• Speech control 🎚 - Ability to change the pitch, duration etc. of generated speech
• Voice conversion / Speech-To-Speech support 🦜 - Streaming support implies real-time S2S; S2T=>T2S does not count
• Longform synthesis - Able to synthesis whole paragraphs

A null value means unfilled/unknown. 🤷‍♂️ Please create pull requests to update the info on the models.
