摘要： The invention is a method for transforming a source individual's voice so as to adopt the characteristics of a target individual's voice. The excitation signal component of the target individual's voice is extracted and the spectral envelope of the source individual's voice is extracted. The transformed voice is synthesized by applying the spectral envelope of the source individual to the excitation signal component of the voice of the target individual. A higher quality transformation is achieved using an enhanced excitation signal created by replacing unvoiced regions of the signal with interpolated data from adjacent voiced regions. Various methods of transforming the spectral characteristics of the source individual's voice are also disclosed.

摘要： Sound signal indicative of a human voice or musical tone is input, and the pitch of the input sound signal is detected. Then, a scale note pitch is determined which is nearest to the detected pitch of the input sound signal. In the meantime, a scale note pitch of an additional sound or harmony sound to be added to the input sound is specified in accordance with a harmony mode selected by a user. The scale note pitch of the additional sound to be generated is modified in accordance with a difference between the determined scale note pitch and the detected pitch of the input sound signal. Because the additional sound is generated with the modified pitch, it can appropriately follow a variation in the pitch of the input sound to be in harmony with the input sound, rather than exactly agreeing with the scale note pitch. As another example, reference scale note pitch data may be supplied, instead of the scale note pitch nearest to the detected pitch of the input sound signal being determined in the above-mentioned manner.
摘要翻译：输入指示人声或音调的声音信号，并且检测输入声音信号的音调。然后，确定最接近输入声音信号的检测音调的音阶音调。同时，根据用户选择的和声模式来指定要添加到输入声音的附加声音或和声的缩放音调音高。要产生的附加声音的音阶音调根据所确定的音阶音调与所输入的声音信号的检测音高之间的差异被修改。由于附加的声音是以修改的音调产生的，所以它可以适当地跟随输入声音的音调的变化与输入声音相一致，而不是完全符合音阶音调。作为另一示例，可以提供参考缩放音调音调数据，而不是以与上述方式确定的输入声音信号的检测音调最接近的音阶音高。

摘要： In accordance with a kind of effect, an effect adding section (38) adds an original microphone signal with an effect signal and outputs the added signal, or outputs an effect signal in place of the original microphone signal. A mixing section (42) mixes the effect signal and the original microphone signal at a variable mixing ratio. The mixed signal is supplied to an echo signal generating circuit (20) to generate an echo signal. An output signal of the effect adding section (38) and the echo signal output from an echo adding section (40) are mixed by a mixing circuit (18). In the case in which both an effect and an echo are added such that the microphone signal and the effect signal are added and then output, the mixing section (42) reduces the mixing ratio of the effect signal, whereby the effect is prevented from being excessively increased.

摘要： The invention relates to a computerized method for correlating a performance, in real time, to a score of music, and a machine based on that method. A score processor accepts a score which a user would like to play and converts it into a useable format. Performance input data is accepted by the input processor and the performance input data is correlated to the score on a note-by-note basis. An apparatus for performing this method includes an input processor that receives input and compares it to the expected score to determine whether an entire chord has been matched, and an output processor which receives a note match signal from the input processor and provides an output stream responsive to the match signals.

摘要： A method for shifting the timbre and/or pitch of an input signal samples the input signal at a first rate and stores the samples in a memory buffer. A digital signal processor resamples the stored input signal at a rate that differs from the first rate at which the input note is originally sampled and stores the resampled input signal in a second memory buffer. A pitch shifter shifts the pitch of the input signal by periodically scaling the resampled input signal by a window function to create an output signal. The rate at which the resampled data is replicated by the window function determines the pitch of the output signal.

摘要： A karaoke apparatus is configured so that, even when a music piece data having no harmony data is to be performed, a harmony voice signal can be generated. Notes of a length not smaller than a quarter note are extracted from a karaoke performance data and a guide melody data of a music piece data. The distributions of frequencies of occurrence of the tones (C to B) are aggregated. The distributions are compared with the major judgment scale and the minor judgment scale. Then, the data is judged to have a key in which the tonic note (scale note) exists at a place where the highest coincidence is attained. A harmony data is generated on the basis of the result of the key judgment and the guide melody data, and a harmony voice signal is produced based on the harmony data.

摘要： In a music apparatus, a generator device has a plurality of channels for concurrently generating various tones. At least, one channel is assigned to generate chorus tones belonging to a multiple of melody parts arranged in parallel to each other. A provider device provides music messages assigned to the plurality of the channels to generate the various tones. The music messages includes a particular music message being assigned to the one channel and being composed of a first music message which contains a note and identifies a melody part to which the note belongs, and a second music message which contains a parameter and identifies a melody part to which the parameter belongs. A controller device controls the one channel of the generator device according to the note and the parameter both belonging to the same melody part so as to generate the chorus tone such that the one channel can generate a chorus tone belonging to a melody part independently from another chorus tone belonging to another melody part.

摘要： A switching apparatus is constructed for discriminating a plurality of singing voices from each other based on a reference melody in order to pass the discriminated singing voices to different audio processes. In the apparatus, a plurality of input devices are provided to collect a plurality of singing voices separately from each other, each input device producing a voice signal which carries an individual melody of the singing voice collected by each input device. A plurality of output terminals are arranged to pass the voice signals separately from each other to the different audio processes. A switch circuit is disposed between the input devices and the output terminals to provide a plurality of electrical paths which are switchable with each other so as to distribute the voice signals from the plurality of the input devices to the plurality of the output terminals through the electrical paths. A controller device examines matching degrees of the individual melodies carried by the voice signals with respect to the reference melody so as to discriminate the voice signals from each other, and controls the switch circuit based on the examined matching degrees to switch the electrical paths to thereby route the discriminated voice signals from the plurality of the input devices to the plurality of the output terminals.
