Abstract: An audio signal transmission apparatus avoiding noise generation is applied to a game platform functions by executing a recording process, and comprises: an analog-to-digital converter, an intermediary processing unit, a counter, and a controlling unit. The analog-to-digital converter is used for converting an analog audio signal to a first digital audio signal. The intermediary processing unit is connected with the analog-to-digital converter for transmitting the first digital audio signal. The counter controls the intermediary processing unit to output the first digital audio signal after counting a specific time. The controlling unit, connected with the counter and the intermediary processing unit, is used for transmitting the first digital audio signal to the game platform. Therefore, the present invention can achieve the purpose for avoiding noise generation when the audio signal transmission apparatus plugs into the game platform.

Abstract: A Chinese speech recognition system and method is disclosed. Firstly, a speech signal is received and recognized to output a word lattice. Next, the word lattice is received, and word arcs of the word lattice are rescored and reranked with a prosodic break model, a prosodic state model, a syllable prosodic-acoustic model, a syllable-juncture prosodic-acoustic model and a factored language model, so as to output a language tag, a prosodic tag and a phonetic segmentation tag, which correspond to the speech signal. The present invention performs rescoring in a two-stage way to promote the recognition rate of basic speech information and labels the language tag, prosodic tag and phonetic segmentation tag to provide the prosodic structure and language information for the rear-stage voice conversion and voice synthesis.
