Problems solved by technology

[0019] It can be seen from the above that the existing mobile phones do not have the voice interaction function between the user and the mobile phone in the true sense
However, the speech recognition and synthesis technology disclosed in the applicant's above-mentioned patent application makes it possible to carry out speech recognition and synthesis of non-specific persons and full syllables of Chinese characters in portable digital mobile communication devices with limited resources while ensuring recognition performance. possible

Embodiment 1

[0070] The operating system with voice interaction function in this embodiment (hereinafter referred to as the voice operating system for short) is composed of a voice recognition part, a voice operation management part and a voice synthesis part. For the hardware resource conditions of the mobile phone 1, the embedded speech recognition and synthesis module is generally controlled within 30MIPS and in the 1M memory space. Such as figure 1 shown.

[0071] The voice recognition part of the voice operating system in this embodiment includes: a voice input module 10 , a feature extraction / compression module 20 and a voice recognition module 30 . Compared with the speech recognition system in the patent application 02148683.2, the speech input module 10 therein corresponds to the analog-to-digital conversion unit in the application, which is used to convert the input speech analog signal into a digital signal; the feature extraction / compression module 20 corresponds to The featu...

Embodiment 2

[0117] The mobile phone voice operating system in this embodiment does not have the function of speech synthesis, but it can realize full-syllable voice recognition, accept voice commands from non-specific people, and can use voice to realize full-syllable input in oriental languages. In terms of system composition, it is the figure 1 The language generation mode and speech synthesis module in the mobile phone are removed, and only output through the existing methods of ordinary mobile phones, such as ringtones, music, vibration, etc. In terms of control methods, compared to Figure 2b , to cancel controls related to voice prompts.

[0118] In addition, the voice recognition part of the present embodiment also includes a tone recognition module, which is used to receive the data of the voice input module 10 in the monosyllable recognition mode, extract the fundamental frequency of the voice signal after the frame-by-frame processing, and according to the whole segment of voic...

Embodiment 3

[0126] The mobile phone voice operating system in this embodiment does not have an oriental language voice input function, but can realize voice recognition and voice prompt functions for command entries of non-specific people. In terms of system composition, it is the figure 1 The phonetic-character conversion and input selection modules in the program are changed to ordinary modules that use keyboards or other methods to realize oriental language input. In terms of control methods, compared to Figure 2b , just cancel the relevant controls on Chinese character input and recognition mode switching. The composition and control of other parts are the same as in Embodiment 1.

[0127] This embodiment also can utilize voice to send note, and the content of note directly adopts pinyin and does not convert into Chinese (or other oriental language) word, although the other side can't see content from screen, can understand by prompting voice. It's as if two people don't nee...

Abstract

The present invention discloses a portable digital mobile communication apparatus with voice operation system and controlling method of voice operation. The feature vector sequences of speech are quantify encoded when the speech is recognized, and in decoding operation, each code in efficiency speech character codes are directly looked up observation probability of on search path from the probability schedule in the decode operation. In association with the present invention, full syllabic speech recognition can be achieved in mobile telephone without the need of training, and input Chinese characters by speech and speech prompting with full syllable. This system comprises semantic analysis, dialogue management and language generation module, and it can also process complicated dialog procedure and feed flexible prompting message back to the user. The present invention can also customize speech command and prompting content by user.

Description

technical field [0001] The invention relates to a digital communication device and its control method and system, in particular to a portable digital mobile device that can be controlled by voice and its voice control method and system. Background technique [0002] Speech recognition and synthesis technology has progressed very rapidly in the past ten years, especially in practical systems. After dozens of years of research accumulation and practical experience, the mainstream algorithms of the speech recognition system have approached unity in the fields of modeling, training, search, and self-adaptation, and most of them use statistics-based continuous probability density hidden Markov models and Viterbi search. In order to obtain a higher degree of naturalness, the speech synthesis system mostly adopts the method of waveform splicing and large-scale sound library, and improves the naturalness by finding the matching segment of the maximum length. The adoption of these m...
