描述

Hi!

I'm trying to train RVC models for a range of dialects in my country. I live in South Africa.

I'm struggling with click-consonant phonemes.

These African language sounds are not understood as phonemic by the model, so transforming voice-to-voice using recordings of African language speakers results in dropped phonemes or incorrect phonemes.

Click consonants are not reliably preserved in the output and are even occasionally replaced by other consonants ("c", "ck", "k").

Is there anyway for me to overcome this roadblock? Do I need to include more of the click-consonants in my training data?

研究方向
The issue reports that click consonant phonemes are dropped or replaced during voice conversion. Examine the model's phoneme dictionary and acoustic model implementation, likely in the model/ or voice conversion/ directories. Review the attached zip file with example audio to understand the failure modes. Check if the training data includes click consonants; if not, consider augmenting the dataset. Engage with maintainers on potential modifications to the phoneme set or preprocessing pipeline. See community comments for any suggested workarounds.
