specific Embodiment approach

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] The present invention uses a statistical model to perform acoustic modeling on notes and time values ​​in music, collects representative humming corpus, calculates observation sample data of notes with a high-precision anti-interference pitch extraction method, and trains them through an iterative method. stable model parameters. Provides a method for re-estimating model parameters, allowing personal humming voices to be used as samples to participate in the retraining of model parameters, so that model parameters can reflect personal pronunciation characteristics and habits, and make the hu...

Abstract

The invention belongs to the technical field of application of computers, and provides a humming music reading method and system based on music note and duration modeling. According to the humming and music reading method and system based on the music note and duration modeling, a music theory gauss mixed model library comprising a music note and music pitch model set and a music note and duration model set is established, model parameter training is carried out on all the models in the music theory gauss mixed model library in advance through a music theory gauss mixed model training unit, and a music theory gauss mixed model library revaluation training unit can be selected to carry out revaluation training on model parameters. When humming music reading is carried out, music pitch characteristic extraction, music theory information decoding recognition, rhythm extraction and music theory processing and conversion are respectively carried out on collected user humming voice, and lastly, a standard music score is output. The humming music reading system is high in recognition rate, good in stability, adaptable to individual singing behavior characteristics and capable of serving as a creation assistant and a backup tool for professional staff and music lovers, and has popularization and application value and industrialization prospects.

Description

technical field [0001] The invention belongs to the field of computer application technology, and in particular relates to a method and system for reading spectrum by humming based on note and time value modeling. The process realizes the function of reading music by humming. Background technique [0002] With the development of computer and network technology, people are increasingly using digital technology to provide music services, such as karaoke, music retrieval, singing evaluation, humming search, music synthesis, etc., which not only enrich people's entertainment life, It also promoted the development of music creation activities. For experienced music lovers, they often sing some melodies impromptu, hoping to find professional software to convert these melodies into song scores and save them for future music original activities. As for professional music creators, they will suddenly be inspired at any time in their lives and sing their own newly conceived melodies...
