KeyError: 'default_speaker'

Both with and without the speaker parameter will result in an error, and the problem lies with the speaker.
May I ask, what is the value of the speaker parameter?

The server from this repo doesn't support the XTTS model. You can use our fork (available via pip install coqui-tts) and corresponding docker images instead.

Hello, I have already run the idiap branch using Docker. I saw in the instructions for the idiap branch that you can clone voice using the following code:

TTS with list of amplitude values as output, clone the voice from speaker_wav

wav = tts.tts(
text="Hello world!",
speaker_wav="my/cloning/audio.wav",
language="en"
）.
But there is no relevant function in server. py that supports this method of cloning speech. Is there a method to implement it in server. py?

[apachexc]

Xtts requires speechr_id.

If I provide the speaker id, the sound produced by cloning will be the speaker id's sound, not the provided speaker wav's sound.

If no speaker_id is provided, an error will occur.
For example, wav=api.tts（
text=text,
speaker_wav=speaker_wav,
language=language
)

How to solve it?
