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, at an identification device, a speech sample from a subject;
performing a signal analysis, via a processor of the identification device, to identify acoustic measures or language markers from the speech sample, wherein performing the signal analysis to identify acoustic measures or language markers from the speech sample comprises identifying the language markers by;
performing an automatic speech recognition process to recognize words, phrases, or sentences;
classifying the recognized words, phrases, or sentences into syntactical categories; and
determining phrase and/or sentence complexity by evaluating a number and order of syntactical categories found in the speech sample;
determining, via the processor, 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.

1. A method for screening for neurological or other diseases, the method comprising:
-
receiving, at an identification device, a speech sample from a subject; performing a signal analysis, via a processor of the identification device, to identify acoustic measures or language markers from the speech sample, wherein performing the signal analysis to identify acoustic measures or language markers from the speech sample comprises identifying the language markers by; performing an automatic speech recognition process to recognize words, phrases, or sentences; classifying the recognized words, phrases, or sentences into syntactical categories; and determining phrase and/or sentence complexity by evaluating a number and order of syntactical categories found in the speech sample; determining, via the processor, 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. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A system for screening for neurological or other diseases, the system comprising:
-
an application service provider for receiving a speech sample from a subject; and one or more storage media having stored thereon computer-executable instructions comprising; 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.

23. A system for screening for diseases, the system comprising:
-
an application service provider for receiving a speech sample from a subject; and one or more storage media having stored thereon computer-executable instructions comprising; a pre-processing module for receiving the speech sample from the application service provider, cleaning the speech sample, and selecting segments of the speech sample for further processing; a speech metric module for receiving the segments of speech sample from the pre-processing module and identifying acoustic measures of the speech sample; and a comparator for comparing the output of the speech metric module with normative data, criteria, or previous output of a coding module stored in a memory of the system and outputting a decision indicating a likelihood and type of disease state, wherein the identified acoustic measures are used as a sole biomarker of the likelihood and type of disease state for the decision indicating the likelihood and type of disease state. - View Dependent Claims (24)

25. A non-transitory 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 stored in a memory to provide an indication of disease diagnosis, wherein the identified acoustic measures are used as a sole biomarker of the indication of disease diagnosis. - View Dependent Claims (26)
