When generating speech from webui, it samples random voice. How can I fix the generated voice ? I can help with a PR.

You can add a reference audio to pin the timbre.

@leng-yue Using reference audio can pin the timbre well, but the speed and pause seem to be random, and reducing the temperature cannot solve the problem.
I hope it can use different punctuation to control the pause time between words and sentences. Sometimes the pauses between sentences are extremely short and unnatural.

Did you include proper puncs in your reference text?

Yes, the reference audio use the high-quality natural voice synthesized by Microsoft Speech, and the reference text also uses reasonable punctuation.
Under the premise of using the same input text, the same default parameters and the same reference audio, the voice generated multiple times has the same timbre, but their speed, prosody or sentence pause time will be different.
For example, the following samples:

Since it's an auto-regressive model, having different speed / porsody across different generation is an expected behavior, does this cause any issue on your side?
