As known in the art, term " speech recognition " refers to words or this field of phrase of discerning user's speech or sing by computer program.Relevant with field of speech recognition is speech control field, and the latter refers to and utilizes computer system to realize the order related with the words of discerning.At Rabiner, Juang has described the various forms of speech recognition systems that for example are used to discern isolated words in " the Fundamentals of Speech Recognition " that published by Prentice-Hall in 1993.For make speech recognition system for form for more sane for the input of singing, can use and sing the acoustic model that generally uses in the training speech recognition system.Replace or in addition, for example can also use as Hosoya, Suzuki, Ito, the maximum likelihood degree linear regression method that Makino describes in the journal of London the 6th International Conference onMusic Information Retrieval (11-15 day in September, 2005) carries out singing the adaptive of data at the acoustic model that utilizes voice training.In addition, several constraints can be used for improving recognition performance, such as to can be as the understanding of the song lyrics of identification grammer, in order to the understanding of the current song position that shows current words and be used for may key word and/or the alternative limited vocabulary table of words.
As mentioned above, Kara OK songs or musical works can comprise a plurality of tracks, and these tracks comprise that musical instrument background music track and optional background are sung the sound track and/or optional leading singer sings the sound track.Yet musical works is musical instrument version or removed and sung sound normally.Musical works for example can be MIDI (musical instrument digital interface) or multiple road digital audio format.That is to say that musical works can comprise the discrete track that has its oneself musical instrument separately.
According to the present invention, track adapter 1121 can be revised the playback of musical works at least with the following methods step 212 (perhaps Fig. 2 d step 231): with track and therefore with the musical instrument noise reduction or remove noise reduction; Melody is changed into another school (for example jazz) from a school (for example grunge); Playback is changed into another song portions (in order to help this change, for example marking the starting position of song portions such as introduction, chapters and sections, chorus and coda in the metadata section of the digital audio file that can more specifically describe hereinafter) from a song portions; Add or removal effect, such as distortion or echo; Increase or reduce the level of effect such as distortion or echo; Increase or reduce playback speed or bat; And increase or reduce the volume that pronunciation is compared with background song.
In addition according to the present invention, can comprise according to context information the modification of the musical works that will use in the Karaoke performance and to select suitably to accompany track.Several versions that each musical works that each personal different music style plays for example, can be arranged.When obtaining context information such as performing artist occupation, can select the accompaniment track of related style.For example, can select the accompaniment track of synthetic popular style at the performing artist who with slip-stick artist is occupation.

During Karaoke performance, equipment 1100 of the present invention observes-sings or the words or the phrase of speech via the speech recognition of being undertaken by speech recognition device 1130 (step 210)-performing artist.When context information obtained device 1110 and detects (step 211) performing artist and be given in the voice commands that comprises in above-mentioned one group of voice commands that limits in advance, track adapter 1121 was carried out the predetermined action related with detected voice commands.For example, when the user called out " more tums ", track adapter 1121 can be removed noise reduction with the track with additional tum.As another example, when the performing artist shouted " being with me to arrive chorus ", playback can jump to the beginning of the chorus part of current musical works.For example can be provided for revising the rule of playback in regular reservoir 1230, these rules for example can be the data files in the hard-drive (not shown in Fig. 1) that is arranged in personal computer 1000.These rules can limit by certain track that activates corresponding MIDI or multiple road digital audio file and carry out voice commands " more tums ".
In addition, equipment 1100 also can have in order to for example to forget the ability of supporting the singer under the situation of song melody the singer.The voice commands that limits in advance that is used for this function for example can be " seeking help ".When activating this order, track adapter 1121 for example can be play the melody as musical instrument or pronunciation version.
In addition, have in voice commands under the situation of the words similar to the lyrics of musical works, equipment 1100 can compare the words of the words that comprises in the lyrics and identification to help avoid the non-required modification to playback.
Alternatively, dedicated button or other such equipment that can provide the user when sending voice commands, to activate.Like this, the user can show that clearly the words of speaking in the pressing button represents voice commands rather than normal the performance to equipment 1100.This can improve performance, because equipment 1100 need not the input of recording of voice constantly and relatively its with the key word vocabulary but in fact clearly indication of the reception key word of speaking.Similarly, this a kind of button or other such equipment can be used for alternatively showing that the user wishes when to revise the words in the lyrics.Therefore, therefore, the user can be before sing replacing the lyrics part activator button.
In embodiment shown in Fig. 2 c, the words of the Karaoke performing artist sounding that carries out current Karaoke performance is carried out speech recognition, step 220.Determine whether the predetermined lyrics partly are identified as with replacing the lyrics in step 221 and partly come sounding.If not, then this method turns back to the step 220 that wherein continues speech recognition.If then when show next time, partly replace at least one predetermined lyrics part that current OK a karaoke club 0K performs, step 222 with the replacement lyrics of sounding.
Embodiments of the present invention shown in Fig. 2 c allow the Karaoke performing artist change-still perform simultaneously the former lyrics that illustrate on current song knowledge-display 1510 to small part.In one embodiment, the performing artist can change the words of predetermine class.For example, the lyrics of many songs comprise name and place name.The Karaoke performing artist for example can change name or the place name of mentioning in musical works.
Words that can be by allowing some classification such as name and place name are replaced by other words implements this point.Can implement speech recognition (step 220) that this point makes equipment 1100 of the present invention be carried out via speech recognition device 1130 and discern that the performing artist sings or words, these words of comparison and the former lyrics (step 221) of speech, if and (in those words that are allowed to change) some words differences, then as long as this words is replaced their (steps 222) in the lyrics that occur once more during the Karaoke performance just illustrating on screen.
Alternatively, system can provide substituting of predetermined number at each words that can replace.Can implement this point with restriction will speech recognition alternative words quantity and for example in noisy environment, increase the robustness of speech recognition.In this case, system is arranged to the words that may substitute identification sounding the words from limited a group.Can use the context information of collection to obtain to be used for substituting of words: for example, can provide from the substituting of the name in performing artist's the contacts list as the name that is used for the lyrics, the place name conduct that can provide the performing artist to visit is used for substituting of place name, or the like.Can illustrate alternatively to the performing artist, the performing artist can will one of substitute (one of words of former words or change) sounding then.When words appeared in the lyrics next time, it was replaced by the version of user's sounding.
For example can be provided for the lyrics of various songs in lyrics reservoir 1220, these lyrics can for example be the texts in the hard disk (not shown in Fig. 1) that is arranged in personal computer 1000.In lyrics reservoir 1220, can be with suitable mode mark name and place name.Can be useful on the mark of all kinds of words that are allowed to replace.In addition, can provide the words the revised reservoir 1250 that comprises following words (for example proper data storehouse), these words are the replacements that are allowed to.For example can organize these words based on above-mentioned mark.
Alternatively, equipment 1100 can be configured to identification when replace with Irene on the sounding male sex's name (perhaps opposite) and thereby the lyrics that showing in " she " replace he (perhaps opposite).
In embodiment shown in Fig. 2 d, get and read or receive outer input data to be used for using step 230 as performance context information.In response, based on getting at least one track that the outer input data of reading or receiving comes adaptive current Karaoke performance, step 231.
In other words, equipment of the present invention 1100 use context information obtain devices 1110 obtain to play Karaoka around the performance place sight (being circumstances and condition) (step 230) and use track adapter 1121 to come adaptive background music track (step 231) based on the character of detected performance context.
As mentioned above, for example can be via keyboard, mouse or another input equipment (not shown in Fig. 1) related with personal computer 1000; Perhaps via the communication network that is connected to personal computer 1000 (not shown in Fig. 1) (such as the Internet or LAN (Local Area Network)); Perhaps for example from external unit (such as sensor component 1300, the mobile device 610 related with the performing artist or with the related mobile device 1620 and 1630 of spectators participant at least one mobile device) receive outer input data as this context information.
Operable sensor component 1300 for example comprises microphone, video camera, positioning equipment (for example GPS equipment) and illumination, humidity, temperature, blood pressure and cardiotach ometer.These sensor components offer context information with data and obtain device 1110, and this acquisitions device can be determined the sight character of playing Karaoka and performing then.Context information obtains device 1110 and also for example can obtain the personal information manager data (comprise as mentioned above and have service data, calendar data and contact list data) on Karaoke performing artist's mobile device 1610 and spectators participant's the mobile device 1620-1630 and use these data to determine performance context via bluetooth.Context information obtains device 1110 also can visit other personal data (such as some pictures of taking the participant time position) for example to determine up-to-date Reiseziel.Context information obtains device 1110 also can visit information about the media file on performing artist and participant's the mobile device 1610-1630, such as their favorite song, artist and/or musical genre.Context information obtains device 1110 also for example can obtain context information by inquiring about with the GPS position from external server.As an example, external server can be provided by near their the style information relevant with school of music that has inhabited (for example in same city) current location or had the music artist of a certain other relation and band with ad-hoc location and provide and will use when adaptive music performance.
