SPEAKER NORMALIZATION THROUGH FORMANT-BASED ...

SPEAKER NORMALIZATION THROUGH. FORMANT-BASED WARPING OF THE FREQUENCY SCALE. Evandro B. Gouvêa and Richard M. Stern. Department of Electrical and Computer ...

Speaker normalization through formant-based warping of the ...

In this paper we study the possible benefits of the use of acoustic features in speaker normalization algorithms using frequency warping.

(PDF) Speaker normalization through formant-based warping of the ...

Speaker normalization techniques modify the spectral representation of incoming speech waveforms in an attempt to reduce variability between speakers. Recent ...

Speaker normalization in speech perception - UC Berkeley Linguistics

The role of vowel formants in vowel perception was also demonstrated by Fry et al. (1962) using a continuum of synthetic vowels. A debate pitting “formant-based ...

About Vowel Normalization - LingTools @ UO

Vowel normalization techniques have been developed because different speakers have different mouth sizes, which in turn causes their formant resonances to ...

A Bayesian approach to speaker normalization using vowel formant ...

A Bayesian approach to speaker normalization using vowel formant frequency. Abstract: Large variation in speakers causes significant performance degradation of ...

SPEAKER NORMALIZATION BASED ON FREQUENCY WARPING

In speech recognition, speaker-dependence of a speech recognition system comes from speaker-dependence of the speech feature, and the variation of vocal tract ...

Speaker-normalized sound representations in the human auditory ...

Therefore, listeners must normalize across speakers without losing linguistic information. Past behavioral work suggests an important role for ...

Intrinsic-cum-extrinsic normalization of formant data of vowels

Using a known speaker-intrinsic normalization procedure, formant data are scaled by the reciprocal of the geometric mean of the first three ...

Speaker dependent changes in formants based on normalization of ...

Formant normalization is made by average formant position given for Czech vowels. For each speaker the center of gravity of two vowel triangles are calculated; ...

Speaker Normalization in Speech Perception - eScholarship

We can then normalize vowel formant measurements relative to vocal tract length, thus removing one of the main sources of the acoustic difference between ...

Comparing vowel formant normalisation procedures

This allows comparability between speakers, as formant values are represented as a proportion of a speaker‟s maximum formant frequency. In effect, speakers‟ ...

Speaker dependent changes in formants based on normalization of ...

The novel method described here uses for formant normalization statistical values of formants presented in the form of formant planes for speaker analysis ...

Evaluating acoustic speaker normalization algorithms - PubMed

Speaker vowel formant normalization, a technique that controls for variation introduced by physical differences between speakers, is necessary in ...

Johnson | The ΔF method of vocal tract length normalization for vowels

Study 2 found that uniform normalization measures (which let each formant serve as a noisy estimator of ΔF) improve vowel classification even ...

Speaker Normalization Based on Subglottal Resonances

In formant-based frequency warping meth- ods, formant positions of different speakers are transformed into a normalized frequency space. In this paper, we ...

University of Alberta Cognitively-Active Speaker Normalization ...

In the third experiment, listeners were trained to report the acoustic correlate associated with increases or decreases to the average formant frequencies ...

Towards an auditory theory of speaker normalization - ScienceDirect

Items with unclear formants were excluded (33 items), leaving 1948 data points for these analyses. The formant values were then normalized to allow ...

Vowel Perception and Speaker Normalization - Will Styler

Lobanov (1971) Normalization · σ is the Standard Deviation of all tokens around the vowel mean · Done for each formant, for each vowel · Leaves you with formant ...

Auditory Sensitivity to Formant Ratios:Toward an Account of Vowel ...

We conclude that these results present an impetus to reconsider formant ratios as a legitimate mechanistic component in the solution to the problem of speaker ...
