Systems and methods of screening for medical states using speech and other vocal behaviors

摘要

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.

主权项

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; anddetermining 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.
