Abstract
The present invention discloses a recognition method for tone change in a Chinese speed sound recognition system. When continuous 'third' pronunciation word connection or identical overlapping word connection is generated in Chinese speech sound (pronunciation), words and sentences with the tone change can be automatically recognized according to the relationship between character strings and word boundaries, and the system identification accuracy can be improved.
Description
Technical field
The present invention relates to the discrimination method of breaking of voice in a kind of Chinese speech identification system, especially refer to a kind of in Chinese speech, automatically according to character string relation and speech circle, coming the identification continuous tone is the language modified tone words and phrases that three word or same word are produced when connecting, and promotes the accuracy of Chinese speech identification system identification.
Background technology
The existing many-sided development of present voice identification system both domestic and external, major part all is the difference at the voice and the meaning of word in the words and phrases in various countries' language, and further discrimination method is provided, and uses the accuracy of promoting System Discrimination; Yet, in the Chinese speech identification system, except that the difference of general polyphone, voice, pronunciation (phonetic notation) causes the puzzlement and degree of difficulty of speech recognition easily, the special circumstances of tonal variations are more arranged, and these situations often become the significant obstacle of speech recognition ability; For example, each Chinese words all has the pronunciation of appointment, comprise " one " (
) sound, " two " (
) sound, " three " (
) sound, " four " (
) sound four kinds of tones and " softly " (
).And in the general Chinese statement, if it is all no problem to read Chinese statement according to " one " sound of the pronunciation (phonetic notation) of individual character to " four " or " softly ", this moment, voice and pronunciation were identical, but comprised the speech of " three " sound word continuously in the while statement, or be used in the identical reduplicated word of appellation, and go up at voice (pronunciation) and just have the situation of changing voice automatically and take place, make between voice and pronunciation to change and difference, and the situation of changing voice is relevant with the number of words of speech again, attempts example and is described as follows several frequently seen situation:
(1) in the middle of the character string of two words, if two words are all " three " sound, then first word is often changed and is read the sound for " two "; As: two word character strings such as " hello ", " thinking you ", and " thinking you " former phonetic notation is (ㄒ ㄧ ㄤ
ㄋ ㄧ
) tone, but (ㄒ ㄧ ㄤ then changed in voice (when reading sound)
ㄋ ㄧ
) tone.
(2) in the middle of triliteral character string, if continuous two " three " sound word is wherein arranged, then first " three " sound word must change thought " two " sound; If three words are " three " sound all, then first word and second word must change thought " two "; As: in the three word character strings of " submarine ", former phonetic notation is (ㄑ ㄧ ㄢ
ㄨ ㄟ
ㄊ ㄧ ㄥ
) tone, but then change into (ㄑ ㄧ ㄢ when reading sound
ㄨ ㄟ
ㄊ ㄧ ㄥ
) tone; And for example: the three word character strings of " president's prize ", former phonetic notation is (ㄗ ㄨ ㄥ
ㄊ ㄨ ㄥ
ㄐ ㄧ ㄤ
) tone, but then change into (ㄗ ㄨ ㄥ when reading sound
ㄊ ㄨ ㄥ
ㄐ ㄧ ㄤ
) tone.
(3) in the middle of the character string of four words, if four words " three " sound all, then first word and the 3rd word must change thought " two "; As: four word character strings such as " very few ", former phonetic notation is (ㄉ ㄧ ㄠ
ㄉ ㄧ ㄠ
ㄜ
ㄨ
) tone, but then change into (ㄉ ㄧ ㄠ when reading sound
ㄉ ㄧ ㄠ
ㄜ
ㄨ
) tone.
(4) in the middle of five words, if five words " three " sound all, then first word and the 3rd, the 4th word must change thought " two "; As: the five word character strings of " 999 99 " (the digital kenel that comprises this example), former phonetic notation is (ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
) tone, but then change into (ㄐ ㄧ ㄡ when reading sound
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
) tone.
(5) if continuously the number of words of " three " sound is an even number, and six words or six words are when above, and per two words in front are one group, according to the pronunciation of continuous two " three "; As: the six word character strings of " 999 999 ", former phonetic notation are (ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
) tone, but then change into (ㄐ ㄧ ㄡ when reading sound
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
ㄐ ㄧ ㄡ
) tone.
(6) if continuously the number of words of " three " sound is an odd number, and seven words or seven words are when above, and per two words in front are one group, and according to the pronunciation of continuous two " three " sound, but last group is three words, according to the pronunciation of continuous three " three "; As: " 5555555 " former phonetic notation is (ㄨ
ㄨ
ㄨ
ㄨ
ㄨ
ㄨ
ㄨ
) tone, but then change into (ㄨ when reading sound
ㄨ
ㄨ
ㄨ
ㄨ
ㄨ
ㄨ
) tone.
As from the foregoing, above-mentioned tonal variations rule is to be applicable to general words and phrases and proper noun, and when having " speech circle " to distinguish in the three word character strings, apply mechanically above-mentioned criterion again after must distinguishing according to " speech circle " earlier, also be applicable to the combination of numeral and normal words, as also be suitable for when being used for " name ", and its tonal variations rule is in addition according to following manner:
(1) when the identification of " name " is used, must separate " surname " and " name ", as " Yo-yo Ma " or " Liu Shuibian ", though three words all " three ", former phonetic notation is (ㄇ ㄚ
ㄧ ヌ
ㄧ ㄡ
) and (ㄉ ㄧ ㄡ
ㄨ ㄟ
ㄅ ㄧ ㄢ
), but " horse ", " willow " are " surname ", do not change tone and equally read " three " sound, " friend friend " or " water is flat " two words are read " two " sound then according to the rule of above-mentioned two continuous " three " sound with first word in two words, and to read be (ㄇ ㄚ so change
ㄧ ㄡ
ㄧ ㄡ
) and (ㄉ ㄧ ㄡ
ㄨ ㄟ
ㄅ ㄧ ㄢ
).
When (2) having " speech circle " to distinguish in other three words character string, as: " president Jiang " or " president's prize " etc., wherein, " president's prize " three words are " three " sound all, and former phonetic notation is (ㄗ ㄨ ㄥ
ㄊ ㄨ ㄥ
ㄐ ㄧ ㄤ
), but because of not comprising " surname ", so still utilize above-mentioned rule, " two " sound read in two words in front, is (ㄗ ㄨ ㄥ so read
ㄊ ㄨ ㄥ
ㄐ ㄧ ㄤ
).And " president Jiang " three words all " three " sound, former phonetic notation is (ㄐ ㄧ ㄤ
ㄗ ㄨ ㄥ
ㄊ ㄨ ㄥ
), but " Jiang " word is " surname ", is not the part of speech, so equally read " three " sound, back two words " president " are then read " two " sound according to above-mentioned two continuous rules of three with first word, are (ㄐ ㄧ ㄤ so read
ㄗ ㄨ ㄥ
ㄊ ㄨ ㄥ
).
When another kind is the appellation of reduplicated word kenel again, promptly be reduplicated word if two identical words are arranged in the appellation of Chinese words and phrases, even if this two word is " three " sound word, voice (pronunciation) are also different, first of reduplicated word read by original sound, and second word will be read to softly.For example: " grandfather ", " grandmother ", " father ", " mother ", " elder brother ", " elder sister ", " younger brother ", " younger sister ", " orangutan " or the like.
In sum, it is the phenomenon that must take place that Chinese words and phrases medium pitch changes, and the otherness of voice that tonal variations forms and pronunciation obviously can increase the degree of difficulty and the incorrectness of speech recognition, cause the puzzlement in the actual use, as: in a Chinese speech identification system, be to utilize the pronunciation mode to import a Chinese database earlier, utilize voice mode that one Chinese words and phrases (or character string) are imported in this voice identification system again, the phase identification of this voice identification system of energy mat is handled, use and can from Chinese database, capture correct Chinese words and phrases or signal and output, to reach the convenience of speech control; Yet, during actual the use, in the often same Chinese words and phrases (or character string), voice are because of the relation of changing voice is different with pronunciation, and causing can't correct Chinese words and phrases or the signal of simple and easy output, cause the difficulty or the mistake of speech recognition, also influence the carrying out of subsequent job, examination is lifted actual example again and is described as follows:
