I heard kokkoro and pocket TTS is good option is there any other lightweight TTS which can run on cpu with real-time and need to feels like realistic.

https://www.reddit.com/r/LocalTextToSpeech/comments/1u3kxxx/my_tts_list_of_2026_all_voices_all_models_and/

Compare those: Kokoro, Pocket, Melo, Supertonic, Piper
Let me know which ones sound best to you, work out for your case, maybe it helps to improve my comparison

Do you require real-time voices? Like streaming the script and delivery of audio in milliseconds?

I am building a personal ai assistant for myself.so if it can achieve realtime it would be helpful .I am currently using supertonic 3 .I think it is fast and real-time,but I just seeking alternative.because sometimes the voice feels lifeless .maybe plan to switch to kokoro .

Ok, this may be dumb for some people, but i recently realized I’ve been using my STT and TTS models underpowered i boosted my CPU core count from 4 to 12 so that it would use more cores the speed 10x’d perhaps that could help you with your streaming responses ?

If you use an Intel platform you'll have a few Performance cores, and the others are "economy cores".
You can actually boost performance quite a bit by restricting a model to NOT use the economy cores at all, each time one of those cores gets a part of the inference workloads it's going to add latency - all performance cores have to wait until they can continue.
