The invention discloses a traffic domain service voice adaptive generation method and
system based on a thinking chain fine-tuning
large model, and the method comprises the steps: converting an input voice
signal into a high-dimensional voice feature
signal through a voice
encoder, and generating a text output
signal according to the high-dimensional voice feature signal through a text decoder and a
pinyin decoder; according to the invention, a variational de-quantization joint data enhancement mechanism, a dual-channel multi-mode
discriminator architecture and a layered composite
loss function are adopted to carry out high-fidelity emotional
speech generation and robustness synthesis in a complex
noise environment, and semantic-driven dynamic
rhythm optimization and professional term precise pronunciation are synchronously supported; in an application scene in the traffic field, a multi-task
speech recognition method can be adopted to realize efficient linkage of character-level recognition, audio-to-
pinyin conversion and
sentence-level accent classification modules, so that complex accent, more
noise and traffic term polyphone challenges are effectively handled, and the method is suitable for being widely popularized and used.
