             If set to float < 1, only the smallest set of most probable tokens with probabilities that add up to top_p or higher are kept for generation.

-        cond_free_k (float):
-            Knob that determines how to balance the conditioning free signal with the conditioning-present signal. [0,inf].
-            As cond_free_k increases, the output becomes dominated by the conditioning-free signal.
-            Formula is: output=cond_present_output*(cond_free_k+1)-cond_absenct_output*cond_free_k. Defaults to `2.0`.

-        diffusion_temperature (float):
-            Controls the variance of the noise fed into the diffusion model. [0,1]. Values at 0
-            are the "mean" prediction of the diffusion network and will sound bland and smeared.

-
         num_gpt_outputs (int):
             Number of samples taken from the autoregressive model, all of which are filtered using CLVP.
             As XTTS is a probabilistic model, more samples means a higher probability of creating something "great".
             Defaults to `16`.
 
-        decoder_iterations (int):
-            Number of diffusion steps to perform. [0,4000]. More steps means the network has more chances to iteratively refine
-            the output, which should theoretically mean a higher quality output. Generally a value above 250 is not noticeably better,
-            however. Defaults to `30`.
-
-        decoder_sampler (str):
-            Diffusion sampler to be used. `ddim` or `dpm++2m`. Defaults to `ddim`.
-
         gpt_cond_len (int):
             Secs audio to be used as conditioning for the autoregressive model. Defaults to `3`.
