Abstract
The utility model discloses an audio evaluating device which comprises a cepstral parameter analysis module (11), a driver element characteristic comparison module (12) and an audio track characteristic comparison module (13), wherein the output of the cepstral parameter analysis module (11) is connected with the input of the driver element characteristic comparison module (12) and the input of the audio track characteristic comparison module (13) respectively. The audio evaluating device can objectively and accurately evaluate the acoustic quality of the song sung by the participator, that is, the audio evaluating device can judge whether the participator sings out of tune and simultaneously judge whether the participator sounds like the original singer.
Description
Technical field
The utility model relates to a kind of device that audio frequency is compared.
Background technology
In variety show or electronic game, the form that the participant sings popular song can appear, and can evaluate and test marking by a cover audio frequency evaluating apparatus this moment usually.Study carefully its principle, existing audio frequency evaluating apparatus is whether key elements such as the pitch, loudness of a sound, accuracy in pitch, tone color of each note of the audio frequency sung of comparison participant are consistent with original song melody.But whether similar for the audio frequency that the participant sang to original singer's audio frequency of original singer, but do not carry out objective, evaluation and test accurately.
At present existing Application on Voiceprint Recognition (Voiceprint Recognition) technology belongs to a kind of of biological identification technology, is a speech parameter according to reflection speaker's physiology and behavioural characteristic in the speech waveform, discerns the technology of speaker ' s identity automatically.Different with speech recognition is, the purpose of Application on Voiceprint Recognition is to judge whom the speaker is, and the purpose of speech recognition is the speech content that identifies in the voice signal.
The utility model content
Technical problem to be solved in the utility model provides a kind of audio frequency evaluating apparatus, whether with original song melody consistent, whether can compare the audio frequency that the participant sings again similar with original singer's performance if both can compare the audio frequency that the participant sings.
For solving the problems of the technologies described above, the utility model audio frequency evaluating apparatus comprises the cepstrum parameter analysis module, driver element feature comparison module and sound channel characteristic comparison module, the output of described cepstrum parameter analysis module connect the input of described driver element feature comparison module and the input of described sound channel characteristic comparison module respectively.
The utility model can carry out objective, evaluation and test exactly to the tone color that the participant gave song recitals, and judges that promptly its song of singing is accurate inaccurate, judges again between itself and the original singer to like.
Description of drawings
Fig. 1 is the structural representation of the utility model audio frequency evaluating apparatus;
Fig. 2 is the use synoptic diagram of the utility model audio frequency evaluating apparatus.
Description of reference numerals among the figure:
10 is the audio frequency evaluating apparatus; 11 is the cepstrum parameter analysis module; 12 is driver element feature comparison module; 13 is sound channel characteristic comparison module; 21,22,23,24,25 be respectively step 1,2,3a, 3b, 4.
Embodiment
See also Fig. 1, the utility model audio frequency evaluating apparatus 10 comprises cepstrum parameter analysis module 11, driver element feature comparison module 12 and sound channel characteristic comparison module 13, and wherein the output of cepstrum parameter analysis module 11 is connected respectively to the input of driver element feature comparison module 12 and the input of sound channel characteristic comparison module 13.
People's speech waveform be by driving source feature and sound channel characteristic common decision.So-called driving source feature is exactly phonetic features such as pitch, loudness of a sound, accuracy in pitch, tone color.Physiology key elements such as the shape that so-called sound channel characteristic is exactly people's a sound channel, size.The sound wave that the people sent is actually the long-pending of driving source feature and sound channel characteristic.By the cepstrum parameter analysis, driver element feature in the sound wave and sound channel characteristic can be separated.In the utility model, cepstrum parameter analysis module 11 is exactly that the driving source feature and the sound channel characteristic that are used for audio frequency that the singer is sung are separated, and the driving source feature after will separating sends driving source feature comparison module 12 to, sends the sound channel characteristic after separating to sound channel characteristic comparison module 13.
Whether record the melodic information of song in the described driving source feature comparison module 12, it is consistent with the melodic information of song to be used for more isolated driving source feature (pitch, loudness of a sound, accuracy in pitch, tone color etc.).
Record original singer's channel information in the described sound channel characteristic comparison module 13, whether the sound channel characteristic after being used for relatively separating is similar with original singer's sound channel characteristic.Described sound channel characteristic comparison module 13 emphasis utilization Application on Voiceprint Recognition technology.
See also Fig. 2, the using method of the utility model audio frequency evaluating apparatus is as follows:
At first, the melodic information of song should be stored in the driving source feature comparison module 12 in advance, original singer's channel information should be stored in the sound channel characteristic comparison module 13 in advance.
In the 1st step 21, variety show or electronic game participant give song recitals;
In the 2nd step 22, the audio frequency that is given song recitals sends to cepstrum parameter analysis module 11, and the driving source feature of isolating wherein sends to driving source feature comparison module 12, and the sound channel characteristic of isolating wherein sends to sound channel characteristic comparison module 13;
In the 3a step 23, whether the driving source feature in driving source feature comparison module 12 song that relatively participant sang is consistent with the melodic information of song, i.e. " it is inaccurate to carry a tune ";
In the 3b step 24, whether sound channel characteristic in sound channel characteristic comparison module 13 song that relatively participant sang and original singer's channel information be similar, promptly " sings to such an extent that like ";
In the 4th step 25, driving source feature comparison module 12 provides driving source feature evaluation and test mark, and sound channel characteristic comparison module 13 is given sound channel characteristic evaluation and test mark, and a whole set of audio frequency evaluating apparatus provides comprehensive mark.
In sum, whether the utility model both can compare the audio frequency that the participant sings consistent with original song melody, and whether can compare the audio frequency that the participant sings again similar with original singer's performance.
Claims (1)
1. audio frequency evaluating apparatus, it is characterized in that, comprise cepstrum parameter analysis module (11), driver element feature comparison module (12) and sound channel characteristic comparison module (13), the output of described cepstrum parameter analysis module (11) connect the input of described driver element feature comparison module (12) and the input of described sound channel characteristic comparison module (13) respectively.
