Speech Compression and Synthesis

Effect of MPEG audio compression on HMM-based speech synthesis

In this paper, the effect of MPEG audio compression on HMMbased speech synthesis is studied. Speech signals are encoded with various compression rates and analyzed using the GlottHMM vocoder. Objective evaluation results show that the vocoder parameters start to degrade from encoding with bitrates of 32 kbit/s or less, which is also confirmed by the subjective evaluation of the vocoder analysis...

بررسی درک گفتار با فشردگی زمانی در سالمندان

Objectives: Most of the studies performed on aging and auditory system have historically focused on speech perception disorders in elderly people. According to studies, speech discrimination disorders in aged people usually result from auditory temporal processing impairment. Our study was done to determine the ability of aged people to discriminate time compressed speech. Methods & Material...

Study on Unit-Selection and Statistical Parametric Speech Synthesis Techniques

One of the interesting topics on multimedia domain is concerned with empowering computer in order to speech production. Speech synthesis is granting human abilities to the computer for speech production. Data-based approach and process-based approach are the two main approaches on speech synthesis. Each approach has its varied challenges. Unit-selection speech synthesis and statistical parametr...

Low Resource TTS Synthesis Based on Cepstral Filter with Phase Randomized Excitation

In this paper we present the acoustic synthesis of a low resource Text-To-Speech (TTS) system based on a 7th order cepstral filter. The excitation signal is designed in frequency domain by a two parameter model. This model is able to generate the excitation signal for both, voiced and unvoiced segments. The sets of filter coefficients represent the speech units and are stored in a compressed fo...
