Researchers have investigated the Mimi codec, a component of the Moshi language model, focusing on its 2048-token semantic codebook. Their findings indicate that standard ABX experiments are insufficient for understanding the relationship between semantic tokens and their phonetic realizations. By aligning Mimi representations with TIMIT corpus transcriptions, the study demonstrates that these semantic tokens correspond to various phonetic units, including quadphones, triphones, biphones, phones, and subphones.
