New harmonicity measures for pitch estimation and voice activity detection
نویسندگان
چکیده
Harmonic structure can be easily recognized in the timefrequency representation of speech signals even in the diverse environment. The harmonicity is a measure of the completeness of harmonic structure. This paper extends the use of conventional harmonicity measure to the tasks of pitch estimation and voice activity detection. A set of hierarchical harmonicities, including grid, temporal, spectral and segmental harmonicities, is derived for this purpose. A series of experiments are conducted to show the effectiveness of using harmonicities in speech processing.

Pitch Estimation by the Pair-Wise Evaluation of Spectral Peaks
In this paper, a new approach for pitch estimation in polyphonic musical audio is presented. The algorithm is based on the pair-wise analysis of spectral peaks. The idea of the technique lies in the identification of partials with successive (odd) harmonic numbers. Since successive partials of a harmonic sound have well defined frequency ratios, a possible fundamental can be derived from the in...
متن کاملA New Algorithm for Voice Activity Detection Based on Wavelet Packets (RESEARCH NOTE)
Speech constitutes much of the communicated information; most other perceived audio signals do not carry nearly as much information. Indeed, much of the non-speech signals maybe classified as ‘noise’ in human communication. The process of separating conversational speech and noise is termed voice activity detection (VAD). This paper describes a new approach to VAD which is based on the Wavelet ...
متن کاملExploiting Frequency, Periodicity and Harmonicity Using Advanced Time-Frequency Concentration Techniques for Multipitch Estimation of Choir and Symphony
To advance research on automatic music transcription (AMT), it is important to have labeled datasets with sufficient diversity and complexity that support the creation and evaluation of robust algorithms to deal with issues seen in real-world polyphonic music signals. In this paper, we propose new datasets and investigate signal processing algorithms for multipitch estimation (MPE) in choral an...
متن کاملComparisons of Harmony and Rhythm of Japanese and English through Signal Processing
Japanese and English speech structures are different in terms of harmony, rhythm, and frequency of sound. Voice samples of 5 native speakers of English and Japanese were collected and analyzed through fast Fourier transform, autocorrelation, and statistical analysis. The harmony of language refers to the spatial frequency content of speech and is analyzed through two different measures, Harmoni...
متن کاملAdaptive Harmonic Spectral Decomposition for Multiple Pitch Estimation Emmanuel Vincent, Nancy Bertin and Roland Badeau
Multiple pitch estimation consists of inferring the fundamental frequencies and the salience of the notes forming a music signal over short time frames. This mid-level representation can be exploited as a front-end for higher-level applications, such as music-to-score transcription or chord detection. One approach is to decompose the short-term magnitude spectrum of the signal into a sum of bas...
