Embodiment Construction

[0029] The embodiment developed by the humming recognition and arrangement system and method of the present invention will be described in detail later.

[0030] Please refer to figure 1 , the humming transcription system (humming transcription system) 10 of the present invention includes a humming signal input interface (humming signal input interface) 12, usually a microphone or any sound receiving device, which is passed through the user's "humming" or "Sing" to receive the acoustic signal. Among them, such as figure 1 As shown, the best situation of the humming arrangement system 10 is to be arranged in a calculator, such as a personal computer (not shown in the figure), etc. However, it can be changed, and the humming arrangement system 10 can also be independently arranged outside the calculator Then connect with the calculator through the interconnection interface. Both of these two implementation modes can be included in the scope of the technical solution proposed ...

Abstract

A humming composition system and its method can compose the input humming signal into a standard score and present it again. The present invention uses a statistical music recognition method to identify the input humming signal, shape the input humming signal into musical notes, and determine the pitch value of each musical note in the input humming signal. The humming composition system of the present invention comprises an input device, a humming database and a statistical humming composition block, wherein the input device is used to receive the input humming signal, and the humming database records a series of The humming data is used for training note models and pitch models, while the statistical humming arrangement block writes the input humming signal into a music score, and the note symbols in the input humming signal are determined by the single-tone level model, while the pitch values ​​of the note symbols are shaped by a Gaussian mixture model to output music query sequences for music retrieval in the subsequent music search step.

Description

technical field [0001] The present invention relates to a humming arrangement system and method thereof, in particular to a system that can adapt an input humming signal into a recognizable musical representation (musical representation) to satisfy the task of searching for music in a music database Demanding humming arrangement system and method thereof. Background technique [0002] For modern people who need to run around in busy jobs to make a living, moderate recreation and entertainment are important factors to relax their bodies and make them energetic. Music is generally considered as an inexpensive pastime that can relieve physical and mental stress and soothe people's souls. With the advent of digital sound processing technology, the presentation of music creation can exist in a variety of changeable rules Among them, for example, the presentation of music can be retained in analog form on audio tapes, or it can also be reproduced in the form of digital sound effe...
