semantic_prompt explanation in Prompt Format is confusing. Could you explain more?

[yurtmete]

semantic_prompt is explained as "The semantic_prompt array contains a sequence of token IDs generated by the BERT tokenizer from Hugging Face. " in https://github.com/suno-ai/bark/tree/main/bark/assets/prompts#prompt-format

Could the definition be wrong? Because if we look at full_generation definition in here: https://github.com/suno-ai/bark/blob/1ad007171e0c46078eb6d3afb6db4daf0c4f41cd/bark/api.py#LL67C5-L72C10

the semantic_prompt is actually the output of the first GPT model (semantic tokenizer). Or am I missing something?
