SYSTEMS AND METHODS OF SCREENING FOR MEDICAL STATES USING SPEECH AND OTHER VOCAL BEHAVIORS
First Claim
1. A method for screening for neurological or other diseases, the method comprising:
- receiving a speech sample from a subject;
performing a signal analysis to identify acoustic measures or language markers from the speech sample;
determining a likelihood and type of disease state based upon the identified acoustic measures or language markers; and
outputting the likelihood and type of disease state.

Abstract
Systems and methods of screening for neurological and other diseases utilizing a subject'"'"'s speech behavior are provided. According to one embodiment, a system is provided that includes an identification device used to determine a health state of a subject by receiving, as input to an interface of the device, one or more speech samples from the subject. The speech samples can be provided to the device by an intentional action of a user or passively due to the device being in the signal path of the subject'"'"'s speech. The samples are communicated to a processor that identifies the acoustic measures of the samples and compares the acoustic measures of the samples with baseline acoustic measures stored in a memory of the device. The results of this determination can be communicated back to the subject or provided to a third party.

23. A system for screening for neurological or other diseases, the system comprising:
-
an application service provider for receiving a speech sample from a subject; a pre-processing module for receiving the speech sample from the application service provider and cleaning the speech sample or selecting segments of the speech sample for further processing; a speech metric module for receiving the speech sample from the pre-processing module and identifying acoustic measures of the speech sample; a language marker module for receiving the speech sample from the pre-processing module, performing automatic speech recognition;
classifying recognized words, phrases, or sentences into syntactical categories; and
determining phrase and/or sentence complexity;a coding module for combining acoustic measures and/or language markers obtained by the speech metric module and the language marker module; and a comparator for comparing the output of the coding module with normative data, criteria, or previous output of the coding module stored in a memory of the system and outputting a decision indicating a likelihood and type of disease state.

26. A computer-readable medium comprising instructions stored thereon for performing a method for screening for neurological or other diseases, the instructions comprising steps for:
-
receiving a speech sample, segmenting the speech sample into windows and performing pattern recognition to locate a particular pattern in each window; identifying acoustic measures of the speech sample including characteristics of the particular pattern; and comparing the acoustic measures of the speech sample including the characteristics of the particular pattern with normative data, criteria, or previous output of the coding module stored in a memory of the system to provide an indication of disease diagnosis; - View Dependent Claims (27)
