Audio tokenization using WavTokenizer (processing 75 tokens per second) 2. CTC forced alignment for precise word-to-audio token mapping 3. Structured prompt creation following the format: [full transcription] [word] [duration token] [audio tokens] https://www.outeai.com/blog/OuteTTS-0.1-350M Being an experimental v0.1 release, there are some known issues: - Vocabulary constraints due to training data limitations - String-only input support - Given its compact 350M parameter size, the model may frequently alter, insert, or omit wrong words, leading to variations in output quality. - Variable temperature sensitivity depending on use case - Performs best with shorter sentences, as accuracy may decrease with longer inputs Listen to samples generated by OuteTTS-0.1-350M: Your browser does not support the audio element.
