Voice-controlled electronic musical instrument

(57) A summary and subject Offer the voice controlling expression musical instrument of the form factor which most often expresses the actual musical instrument which an electronic instrument expresses. Means The present invention is an electronic sound voice control musical instrument. This is essentially electronic Cazeau. A player hums in a mouthpiece, and this equipment copies the sound of a musical instrument, and that pitch and volume change according to a player's voice. The impression controlled as an impression which is playing the actual musical instrument, and its musical instrument are considered by the fine nuance of their voice is given to a player. Arbitrary music generation sound sources, such as a source of supply of arbitrary sounds, may be substantially, such as a trumpet, a trombone, a clarinet, a flute, a piano, an electric guitar, voice, a whistle and also a chorus, sufficient as a musical instrument fundamentally. In the simplest composition, the musical instrument resembles a certain kind of phon. However, if needed, the manufacturer can also make the form and appearance of a musical instrument so that it may be made in agreement with the sound of arbitrary traditional musical instruments, but he can also completely make the form new. The functional requirements of a physical design of the present invention are only a portable thing, having a mouthpiece containing a player's voice, having one or more loudspeakers by which a sound is generated, and having a main part which an electronic circuit and a battery are stored and can arrange a finger operation type control section. The three main software configuration elements of the present invention are a frequency detection module, a loudness pursuit module, and a note attack module. A frequency detection module (FDM) identifies the frequency of a player's voice. This analyzes the sound wave which entered and is performed by discovering a circulation-shaped pattern. This method is a new combination with high autocorrelation and zero crossing, or calculation efficiency of pitch detection of a peak and -. The selected musical instrument is compounded by the offset from the pitch demanded by the pitch or player determined by FDM. A loudness pursuit component measures the loudness of a player's voice, next sets up the volume of a synthetic sound using this information. A note attack module detects a sudden change of the loudness a player's voice. This component supports the determination of when the compounded musical instrument must start a new note.
