Male voices lisping after clone?

[hrhdegenetrix]

Just checking in since most people are probably cloning female voices, so I sincerely do not know if this is a known issue. I have a non-lisping male voice I am trying to replicate using OpenVoice, and it sounds okay, but he's lisping now. This is especially pronounced in 'cheerful' and 'friendly', where for lack of a better term there is an obvious 'effeminate' quality, but also evident in 'default' and all variations. I have tried different samples of varying lengths, and I should note that the sample voice demonstrably does not have a lisp. I've tried with en_newest, en-br, en-us, etc. However, all results are unsatisfactory. Are there any tips for mitigating this? Is this a known effect? Would love to use OpenVoice because it is very fast and its control over tone allows for a lot of nuance, but in this one very distinct and distracting way it seems to struggle and I'm not sure how to overcome it.
