	## Legend

	For the [above](#) TTS capability table. Open the [viewer](../../viewer/) in another window or even another monitor to keep both it and the legend in view.

	* 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](https://en.wikipedia.org/wiki/International_Phonetic_Alphabet) - International Phonetic Alphabet
	* [ARPAbet](https://en.wikipedia.org/wiki/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](https://elevenlabs.io/docs/speech-synthesis/prompting#emotion)
	* Streaming support 🌊 - Can playback audio while it is still being generated
	* Speech control 🎚 - Ability to change the pitch, duration, etc. for the whole and/or per-phoneme of the generated speech
	* Voice conversion / Speech-To-Speech 🦜 - Streaming support implies real-time S2S; S2T=>T2S does not count
	* Longform synthesis 📜 - Able to synthesize whole paragraphs, as some TTS models tend to break down after a certain audio length limit

	Example if the proprietary ElevenLabs were to be added to the capabilities table:
	\| Name \| Processor<br>⚡ \| Phonetic alphabet<br>🔤 \| Insta-clone<br>👥 \| Emotional control<br>🎭 \| Prompting<br>📖 \| Speech control<br>🎚 \| Streaming support<br>🌊 \| Voice conversion<br>🦜 \| Longform synthesis<br>📜 \|

	Please create pull requests to update the info on the models.

	## Legend

	For the [above](#) TTS capability table. Open the [viewer](../../viewer/) in another window or even another monitor to keep both it and the legend in view.

	* 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](https://en.wikipedia.org/wiki/International_Phonetic_Alphabet) - International Phonetic Alphabet
	* [ARPAbet](https://en.wikipedia.org/wiki/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](https://elevenlabs.io/docs/speech-synthesis/prompting#emotion)
	* Streaming support 🌊 - Can playback audio while it is still being generated
	* Speech control 🎚 - Ability to change the pitch, duration, etc. for the whole and/or per-phoneme of the generated speech
	* Voice conversion / Speech-To-Speech 🦜 - Streaming support implies real-time S2S; S2T=>T2S does not count
	* Longform synthesis 📜 - Able to synthesize whole paragraphs, as some TTS models tend to break down after a certain audio length limit

	Example if the proprietary ElevenLabs were to be added to the capabilities table:
	\| Name \| Processor<br>⚡ \| Phonetic alphabet<br>🔤 \| Insta-clone<br>👥 \| Emotional control<br>🎭 \| Prompting<br>📖 \| Speech control<br>🎚 \| Streaming support<br>🌊 \| Voice conversion<br>🦜 \| Longform synthesis<br>📜 \|
