A wireless digital audio system includes a portable audio source with a digital audio transmitter operatively coupled thereto and an audio receiver operatively coupled to a headphone set. The audio receiver is configured for digital wireless communication with the audio transmitter. The digital audio receiver utilizes fuzzy logic to optimize digital signal processing. Each of the digital audio transmitter and receiver is configured for code division multiple access (CDMA) communication. The wireless digital audio system allows private audio enjoyment without interference from other users of independent wireless digital transmitters and receivers sharing the same space.

A system and method for semantic analysis of speech, the semantic speech analysis system being used for implementing semantic analysis of speech in a preset field, comprising: a storage unit (1), used for storing semantic sentences in the preset field, each semantic sentence corresponding to an address, the semantic sentences comprising characters and keywords, each keyword corresponding to a tag, and a word list being prearranged in the storage unit (1), used for storing the address of the semantic sentence in which each word appears and/or the address of the semantic sentence in which each tag appears; an acquisition unit (2), used for acquiring speech sentences to be analysed; an indexing unit (3), being respectively connected to the storage unit (1) and the acquisition unit (2), and being used for searching the semantic sentences in the storage unit (1) on the basis of the speech sentences to be analysed, acquiring candidate semantic sentences matching the speech sentences to be analysed and a corresponding candidate order; and an analysis unit (4), connected to the indexing unit (3), and being used for using a fuzzy match algorithm, on the basis of the sorted candidate sentences, to analyse the speech sentences to be analysed, and acquiring analysis results.

Systems and processes are disclosed for discovering trending terms in automatic speech recognition. Candidate terms (e.g., words, phrases, etc.) not yet found in a speech recognizer vocabulary or having low language model probability can be identified based on trending usage in a variety of electronic data sources (e.g., social network feeds, news sources, search queries, etc.). When candidate terms are identified, archives of live or recent speech traffic can be searched to determine whether users are uttering the candidate terms in dictation or speech requests. Such searching can be done using open vocabulary spoken term detection to find phonetic matches in the audio archives. As the candidate terms are found in the speech traffic, notifications can be generated that identify the candidate terms, provide relevant usage statistics, identify the context in which the terms are used, and the like.

A method and a system for voice transmission control. The method comprises: receiving, by a voice answering device, a voice command and transmitting the voice command to a sound control server through a network data transmission channel; recognizing, by the sound control server, the voice command, generating corresponding second VXML control information based on a recognition result, and transmitting the second VXML control information to the voice answering device through the network data transmission channel; and performing, by the voice answering device, an operation according to the received second VXML control information. With this method, the architecture and workflow of the communication system can be simplified, and the difficulty of design thereof can be reduced.
