Enhancement of alaryngeal speech by adaptive filtering
Arti cial larynxes enable adequate communication for people who are unable to use their larynxes. However, the resulting speech has an unnatural quality and is signi cantly less intelligible than normal speech. One of the major problems with the widely-used Transcutaneous Arti cial Larynx (TAL) is the presence of a steady background noise due to the leakage of acoustic energy. In the present st...
متن کاملspeech enhancement based on spectral subtraction and genetic programming
in this paper, genetic programming is applied for quality improvement of noisy speech signal. therefore, a system including both spectral subtraction and genetic programming is implemented for speech enhancement. in the proposed method, first noise is reduced by spectral subtraction. in the next step, genetic programming trees are trained for more enhancement of noisy signal by mapping the sign...
متن کاملApplication of speech conversion to alaryngeal speech enhancement
Two existing speech conversion algorithms were modified and used to enhance alaryngeal speech. The modifications were aimed at reducing spectral distortion (bandwidth increase) in a vector-quantization (VQ) based system and the spectral discontinuity in a linear multivariate regression (LMR) based system. Spectral distortion was compensated for by formant enhancement using chirp z-transform and...
متن کاملLong-term average spectral characteristics of Cantonese alaryngeal speech.
OBJECTIVE In Hong Kong, esophageal (SE), tracheoesophageal (TE), electrolaryngeal (EL), and pneumatic artificial laryngeal (PA) speech are commonly used by laryngectomees as a means to regain verbal communication after total laryngectomy. While SE and TE speech has been studied to some extent, little is known regarding the EL and PA sound quality. The present study examined the sound quality as...
متن کاملStatistical Voice Conversion Techniques for Alaryngeal Speech Enhancement
This position paper gives a brief overview of our developed technologies for enhancing alaryngeal speech (AL speech) uttered by laryngectomees. There are several alternative speaking methods for laryngectomees to produce AL speech. However, any type of AL speech suffers from lack of naturalness and speaker individuality (identity). To address this issue, we have developed statistical voice conv...
