A 16, 24, 32 kbit/s wideband speech codec based on ATCELP
This paper describes a combined Adaptive Transform Codec (ATC) and Code-Excited Linear Prediction (CELP) algorithm, called ATCELP, for the compression of wideband (7 kHz) signals. The CELP algorithm applies mainly to speech, whereas the ATC mode is selected for music and noise signals. We propose a switching scheme between CELP and ATC mode and describe a frame erasure concealment technique. Su...
متن کاملReal-Time Implementation of Time Domain Harmonic Scaling of Speech for Rate Modification and Coding
Time domain harmonic scaling (TDHS) has been realized in real time on the Bell Laboratories digital signal processing (DSP) integrated circuit. It is an algorithm that can expand or compress the bandwidth and sampling rate of speech by taking advantage of the pitch structure in the speech signal. As such it is useful in a variety of speech applications including speech coding, speech enhancemen...
متن کاملNarrowband perceptual audio coding: enhancements for speech
This paper presents a bi-modal coding paradigm to compress narrowband audio signals at 8 kbit/s. In the general mode, the Enhanced Narrowband Audio Coder (ENPAC) exploits the characteristics of the human hearing system to adaptively code the perceptually important spectral components of the input audio. The other mode is employed to handle audio inputs with a strong harmonic structure. In that ...
متن کاملMilitary Speech Communications over Vocoders in Tandem
Speech intelligibility of two types of vocoders was measured using the modified rhyme test. One type of vocoder, a continuous variable slope delta (CVSD), was a waveform encoder. The other type, an advanced multi-band excitation (AMBE), was a parametric encoder. In the first experiment, clear speech was processed through the vocoders. Intelligibility was measured in a control condition, i.e. wi...
متن کاملEffect 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...
