Speaker normalization in speech perception
Acoustic-phonetic analysis of speech, made practical by the advent of the speech spectrograph (Koenig, Dunn & Lacy, 1946), prompted a number of foundational questions regarding the perception of speech because spectrograms showed that speech is highly variable both within and between talkers. Among early researchers, Liberman et al. (1967) focussed on within-talker variation in the acoustic cue...
متن کاملSpeaker normalization for template based speech recognition
Vocal Tract Length Normalization (VTLN) has been shown to be an efficient speaker normalization tool for HMM based systems. In this paper we show that it is equally efficient for a template based recognition system. Template based systems, while promising, have as potential drawback that templates maintain all non phonetic details apart from the essential phonemic properties; i.e. they retain i...
متن کاملAcross-speaker articulatory normalization for speaker-independent silent speech recognition
Silent speech interfaces (SSIs), which recognize speech from articulatory information (i.e., without using audio information), have the potential to enable persons with laryngectomy or a neurological disease to produce synthesized speech with a natural sounding voice using their tongue and lips. Current approaches to SSIs have largely relied on speaker-dependent recognition models to minimize t...
متن کاملNon-Linguistic Sentence-Length Precursors Affect Speech Perception: Implications for Speaker and Rate Normalization
Speech contexts can influence phonetic perception considerably, even across extended temporal windows. For example, manipulating spectral or temporal characteristics of precursor sentences leads to dramatic changes in categorization of subsequent vowels and consonants (e.g., Ladefoged & Broadbent, 1957; Summerfield, 1981). These findings often have been discussed in terms of speaker and rate no...
متن کاملSpeaker normalization in the perception of Mandarin Chinese tones.
This study investigated speaker normalization in perception of Mandarin tone 2 (midrising) and tone 3 (low-falling-rising) by examining listeners' use of F0 range as a cue to speaker identity. Two speakers were selected such that tone 2 of the low-pitched speaker and tone 3 of the high-pitched speaker occurred at equivalent F0 heights. Production and perception experiments determined that turni...
