APPARATUS AND METHOD FOR SPEECH ANALYSIS
First Claim
1. A method for dote, wining an emotion state of a speaker, comprising:
- providing an acoustic space having one or more dimensions, wherein each dimension of the one or more dimensions of the acoustic space corresponds to at least one baseline acoustic characteristic;
receiving a subject utterance of speech by a speaker;
measuring one or more acoustic characteristics of the subject utterance of speech;
comparing each acoustic characteristic of the one or more acoustic characteristics of the subject utterance of speech to a corresponding one or more baseline acoustic characteristic; and
determining an emotion state of the speaker based on the comparison,wherein determining the emotion state of the speaker based on the comparison occurs within one day of receiving the subject utterance of speech by the speaker.

Abstract
A system that incorporates teachings of the present disclosure may include, for example, an interface for receiving an utterance of speech and converting the utterance into a speech signal, such as digital representation including a waveform and/or spectrum; and a processor for dividing the speech signal into segments and detecting the emotional information from speech. The system is designed by comparing the speech segments to a baseline to identify the emotion or emotions from the suprasegmental information (i.e., paralinguistic information) in speech, wherein the baseline is determined from acoustic characteristics of a plurality of emotion categories. Other embodiments are disclosed.

27. A method for determining an emotion state of a speaker, comprising:
-
providing an acoustic space having one or more dimensions, wherein each dimension of the one or more dimensions of the acoustic space corresponds to at least one baseline acoustic characteristic; receiving a subject utterance of speech by a speaker; measuring one or more acoustic characteristic of the subject utterance of speech; comparing each acoustic characteristic of the one or more acoustic characteristic of the subject utterance of speech to a corresponding one or more baseline acoustic characteristic; and determining an emotion state of the speaker based on the comparison, wherein the emotion state of the speaker comprises at least one magnitude along a corresponding at least one of the one or more dimensions within the acoustic space.

49. A method for determining an emotion state of a speaker, comprising:
-
providing an acoustic space having one or more dimensions, wherein each dimension of the one or more dimensions of the acoustic space corresponds to at least one baseline acoustic characteristic; receiving a training utterance of speech by the speaker; analyzing the training utterance of speech; modifying the acoustic space based on the analysis of the training reference of speech to produce a modified acoustic space having one or more modified dimensions, wherein each modified dimension of the one or more modified dimensions of the modified acoustic space corresponds to at least one modified baseline acoustic characteristic; receiving a subject utterance of speech by a speaker; measuring one or more one acoustic characteristic of the subject utterance of speech; comparing each acoustic characteristic of the one or more acoustic characteristics of the subject utterance of speech to a corresponding one or more one baseline acoustic characteristic; and determining an emotion state of the speaker based on the comparison.

60. A method of creating a perceptual space, comprising:
-
obtaining listener judgments of differences in perception in at least two emotions from one or more speech utterances; measuring d′
values between each of the at least two creations, and each of the remain at least two emotions, wherein the d′
values represent perceptual distances between emotions;applying a multidimensional scaling analysis to the measured d′
values; andcreating a n−
1 dimensional perceptual space.
