Embodiment Construction

[0016] The present invention is a high-precision, hybrid keyboard / ASR structure for handheld devices suitable for:

[0017] (1) Defects of traditional speech recognition technology in harsh environments. For example, the acoustic characteristics of speech become unclear due to erratic noise and channel interference. In addition, the computational and storage workload of traditional techniques is too high, such as full word models, context-sensitive phoneme models, and trigram language models.

[0018] (2) The syllable structure characteristic of some oriental languages ​​in individual sounds of the Korean, Japanese, and Chinese languages. That is, (C)+V, pause, (C)+V, pause, (C)+V, ..., where C represents a consonant, V represents a vowel, and C is optional for Korean, Japanese, and Chinese.

[0019] The present invention will be explained and illustrated by examples in ordinary Chinese. However, those skilled in the art can also apply the principles and purposes of the pre...

Abstract

A method and a device for inputting an oriental language such as Chinese with very high precision for a small-sized electronic device such as a PDA, a mobile telephone set, an electronic dictionary, and an electronic wristwatch having several key pads and/or a memory with small capacity. To further solve the vagueness resulting from the vocalization of each multisyllabic Chinese word in isolated intonation syllables having vowels and consonants separated through automatic syllable recognition and the acoustic realization of Pinyin pronunciation (minor word unit) as, for example, a consonant in adverse environment, the depression of one of specially designed key pads, for example, key pressing operation including the 1st phoneme (consonant or vowel) of a syllable is done. If vagueness remains, the 2nd or 3rd Pinyin pronunciation of the syllable needs to be pressed. The key pads are designed on a data-initiative basis so that the ratio of similarity of phonemes of the respective key pads is minimized and the ratio of similarity of Pinyin pronunciation between keys is maximized.

Description

technical field [0001] The present invention relates to a speech signal processing, especially an automatic speech recognition (ASR) of an oriental language, such as common Chinese, Japanese, Korean, etc., in a hand-held small electronic device with limited storage capacity. Background technique [0002] Automatic speech recognition (ASR) technology has been in development for decades. An example is Large Vocabulary Continuous Speech Recognition (LVCSR) in personal computers. refer to figure 1 , the LVCSR system 1 generally uses an acoustic front-end, which includes a spectral analysis module 15 and a tone analysis 16 for feature extraction, and a pronunciation dictionary with a context-related model and a language model to recognize signals. The computational and storage workload of the LVCSR system 1 is high due to the large number of parameters to be processed for the context relevance model and the language model. For conventional speech recogn...
