(First embodiment)
FIG. 1 is a block diagram showing a schematic functional configuration of a reproduction control device according to a first embodiment of the invention. As shown in FIG. 1 , the reproduction control device 100 includes a lyric data acquisition section 110 , an audio processing section determination section 120 , an audio data acquisition section 130 , an audio reproduction section 140 and an audio processing section 150 . The functions of the above units are realized by a processor operating according to a program in a reproduction control device having a computer hardware configuration, for example. The function of each unit will be further described below.

The lyric data acquisition unit 110 acquires lyric data 111 of a song. More specifically, the lyrics data acquisition unit 110 reads the lyrics data 111 from the storage device. The storage device may be provided in an external device, in which case the lyric data acquisition unit 110 receives the lyric data 111 through wired or wireless communication. The lyric data 111 is, for example, data describing lyrics as text, and is associated with the reproduction position information 111T of the music on a word-by-word or phrase-by-phrase basis. The format of the lyrics data 111 is not particularly limited as long as the words or phrases included in the lyrics can be identified.

Based on the lyric data 111, the voice-processed section determination unit 120 determines voice-processed sections in the song corresponding to specific words or phrases included in the lyrics of the song. More specifically, in the present embodiment, the voice processing segment determination unit 120 determines voice processing segments by referring to a predefined inappropriate term list 121 . The inappropriate term list 121 may allow the user to add or delete arbitrary words. The inappropriate term list 121 defines, for example, words and phrases that are not suitable for reproduction in public places. When a word or phrase included in the inappropriate term list 121 is detected in the lyrics, the voice processing section determination unit 120 determines the word or phrase within the song based on the reproduction position information 111T associated with the word or phrase. Determine the audio processing section.

The audio data acquisition unit 130 acquires audio data 131 of music. More specifically, the audio data acquisition unit 130 reads the audio data 131 from the storage device. As with the lyric data 111, the storage device may be provided in an external device, in which case the audio data acquisition unit 130 receives the audio data 131 through wired or wireless communication. Note that the lyric data 111 and the voice data 131 may be stored in different storage devices. For example, the lyrics data acquisition unit 110 may receive the lyrics data 111 from an external device, and the audio data acquisition unit 130 may read the audio data 131 from the storage device of the reproduction control device 100 .

The audio reproducing unit 140 reproduces the audio data 131 of the music. Specifically, the audio reproducing unit synthesizes an audio signal based on the audio data 131 and outputs the synthesized audio signal to an output device 141 such as a speaker. The output device 141 may be provided in an external device, in which case the audio signal output by the audio reproduction unit 140 is transmitted to the output device 141 by wired or wireless communication.

The audio processing section 150 processes the audio of the music in the audio processing section specified by the audio processing section determining section 120 when the audio reproducing section 140 reproduces the audio data 131 . In this embodiment, the voice processing unit 150 processes the voice of the music so that the words and phrases of the lyrics included in the voice processing section (that is, the words or phrases included in the inappropriate term list 121) cannot be heard. . For example, by applying a filter that cuts the vocal frequency band, by adding reverberation so strong that the lyrics cannot be heard, or by replacing the voice of the song with another voice, words and phrases can be heard. You can process the audio so that it doesn't. The audio reproduction unit 140 may select the type of audio processing as described above, for example, according to the length of the audio processing section.

FIG. 2 is a diagram showing a first example of specifying an audio processing section by the reproduction control device shown in FIG. In the illustrated example, the music reproduction position information 111T associated with the lyric data 111 includes segment IDs into which the music reproduction section is divided, and the time stamp of the start point of each segment. A word or phrase included in the lyrics data 111 is associated with one of the segments. In parts of the song without lyrics, there may be segments that are not associated with words or phrases. In the illustrated example, the playback position information 111T associated with the lyrics data 111 including the lyrics "What the hell is this?" "30"), a segment S2 that is associated with the phrase "the hell" (starting with timestamp "00'10"00"), and a segment S3 that is not associated with a word or phrase (starting with timestamp "00'10 "50") and a segment S4 (starting at time stamp "00'13"10") associated with the phrase "is this?".

Here, for example, assume that the inappropriate term list 121 shown in FIG. 1 includes the word “hell”. In this case, the voice processing section determining unit 120 detects the word "hell" included in the lyrics data 111 by searching with reference to the inappropriate term list 121, and furthermore, the phrase "the hell" including "hell" in the reproduction position information 111T. ” is identified as the audio processing segment. When the audio reproduction unit 140 reproduces the audio data 131 of the music, the audio processing unit 150 reproduces the audio of the music in the segment S2, that is, the interval from the time stamps "00'10"00" to "00'10"50". (illustrated as "EFFECT").

FIG. 3 is a diagram showing a second example of specifying an audio processing section by the reproduction control device shown in FIG. In the illustrated example, the music playback position information 111T associated with the lyric data 111 includes the time stamp of the starting point of the word or phrase included in the lyric. In the illustrated example, the playback position information 111T associated with the lyrics data 111 including the lyrics "What the hell is this?" It includes the timestamp "00'10"00" associated with the phrase "the hell" and the timestamp "00'13"10" associated with the phrase "is this?".

Here, for example, it is assumed that the inappropriate term list 121 includes the word "hell" as in the above example. In this case, the voice processing section determining unit 120 detects the word "hell" included in the lyrics data 111 by searching with reference to the inappropriate term list 121, and furthermore, the phrase "the hell" including "hell" in the reproduction position information 111T. ” is determined as a starting point of the voice processing interval. Here, since the playback position information 111T in the example of FIG. 3 does not clearly indicate the end point of the section corresponding to the word or phrase, for example, the voice processing section determination unit 120 determines that the duration of a predetermined duration from the start point specified by the time stamp. (Duration: 0"50 in the illustrated example). The duration may be set longer for phrases than for words that are associated with the start timestamp. In addition, the duration may be set to be longer according to the number of words included in the phrase.When the audio reproducing unit 140 reproduces the audio data 131 of the music, the audio processing unit 150 uses the time stamp "00 After 0"50 from '10"00', that is, in the interval up to '00'10'50', the sound of the music is processed (illustrated as 'EFFECT').

Note that when the voice processing interval determination unit 120 determines a voice processing interval with a predetermined duration from the time stamp of the starting point as in the example shown in FIG. A processing interval does not necessarily contain an entire word or phrase. However, even in such a case, for example, if a part of a word or phrase cannot be heard, it is difficult to grasp the meaning of the word or phrase as a whole. be able to.

The playback control device 200 shown in FIG. 4 includes a lyric data acquisition unit 110, a voice data acquisition unit 130, a voice reproduction unit 140, and a voice processing unit 150 similar to those of the first embodiment. As a difference from the first embodiment, in the reproduction control device 200, the voice processing section determination section 220 determines the voice processing section according to the word or phrase designating operation acquired on the touch screen display 221. FIG. Here, the touch screen display 221 accepts an operation of designating a lyric display unit that displays the lyrics of the music based on the lyric data 111 acquired by the lyric data acquisition unit 110, and a word or phrase included in the displayed lyrics. It is an example of an operation part.

In the case of this embodiment, instead of referring to a predefined list as in the first embodiment, the voice processing section determination unit 220 allows the user who refers to the image displaying the lyrics to determine the words or phrases contained in the lyrics. Determines the audio processing section according to the operation of specifying . Therefore, there is no need to define a list in advance, and it is possible to control the lyrics more precisely corresponding to the situation in which the music is played.

In another example, the above-described first embodiment and second embodiment are combined, and the voice processing section determination unit refers to a predefined list and determines the voice processing section according to the user's operation. may In this case, for example, additional words or phrases not on the list can be prevented from being heard, and even words or phrases on the list can be heard depending on the situation.
