Harmonic alternatives to sine-wave speech
Sine-wave speech (SWS) is a three-tone replica of speech, conventionally created by matching each constituent sinusoid in amplitude and frequency with the corresponding vocal tract resonance (formants). We propose an alternative technique of starting from a high-quality multicomponent sinusoidal representation, then decimating this model to only three components per frame. In contrast to SWS, t...
متن کاملTemporal Envelopes in Sine-Wave Speech Recognition
There is a long debate on the relative importance of spectral and temporal cues in speech perception theories. On the one hand, the highly-intelligible sine-wave speech (SWS) has been viewed as a representation of the global spectral structure of the speech signal. On the other hand, there is accumulating evidence showing that the temporal aspects of speech without spectral details provide suff...
متن کاملSine-wave speech recognition in a tonal language.
It is hypothesized that in sine-wave replicas of natural speech, lexical tone recognition would be severely impaired due to the loss of F0 information, but the linguistic information at the sentence level could be retrieved even with limited tone information. Forty-one native Mandarin-Chinese-speaking listeners participated in the experiments. Results showed that sine-wave tone-recognition perf...
متن کاملFactors Affecting the Intelligibility of Sine-Wave Speech
Studies on sine-wave speech (SWS) perception suggest that formants contain sufficient information for sentence intelligibility. This study further investigated the effects of amplitude modulation, number of sine-waves, and vowel resonance in SWS recognition. Results showed that Mandarin sentences synthesized using frequency trajectories of the first two formants were highly intelligible with ad...
متن کاملORIGINAL STUDY Envelope Expansion of Sine Wave Vocoded Speech
Cochlear implants are an accepted and effective treatment for restoring hearing sensation to people with severe-to profound hearing loss. Contemporary cochlear implants consist of a microphone, a sound processor, a transmitter, a receiver, and an electrode array that is positioned inside the cochlea. The sound processor is responsible for decomposing the input audio signal into different freque...
