Telephone pathology assessment
First Claim
1. A system for remote assessment of a user comprising:
- application software resident on a server and arranged to interact across a network with a user operating a client device to obtain one or more sample signals of the user'"'"'s speech;
a datastore arranged to store said one or more user speech samples in association with details of the user;
a feature extraction engine arranged to;
extract one or more first features from respective speech samples;
extract one or more second features from one or more reference samples, said reference samples comprising a database of speech samples, each sample having a pathology associated therewith, said pathologies comprising;
normal, neuromuscular pathologic, physical pathologic and mixed pathologic; and
store said second features in association with respective pathologies; and
a comparator arranged to compare said first features extracted from a speech sample with second features extracted from said reference samples and to provide a measure of any differences between said first and second features for assessment of said user.

Abstract
A system for remote assessment of a user is disclosed. The system comprises application software resident on a server and arranged to interact across a network with a user operating a client device to obtain one or more sample signals of the user'"'"'s speech. A datastore is arranged to store the user speech samples in association with details of the user. A feature extraction engine is arranged to extract one or more first features from respective speech samples. A comparator is arranged to compare the first features extracted from a speech sample with second features extracted from one or more reference samples and to provide a measure of any differences between the first and second features for assessment of the user.

7. A system for remote assessment of a user comprising:
-
application software resident on a server and arranged to interact across a network with a user operating a client device to obtain one or more sample signals of the user'"'"'s speech, said sample signals comprising a sustained phonation of the vowel sound /a/; a datastore arranged to store said one or more user speech samples in association with details of the user; a feature extraction engine arranged to;
extract one or more first features from respective speech samples;
extract one or more second features from one or more reference samples, said reference samples comprising a database of speech samples, each sample having a pathology associated therewith; and
store said second features in association with respective pathologies; anda comparator arranged to compare said first features extracted from a speech sample with second features extracted from said reference samples and to provide a measure of any differences between said first and second features for assessment of said user. - View Dependent Claims (8)

9. A system for remote assessment of a user comprising:
-
application software resident on a server and arranged to interact across a network with a user operating a client device to obtain one or more sample signals of the user'"'"'s speech; a datastore arranged to store said one or more user speech samples in association with details of the user; a feature extraction engine arranged to extract one or more first features from respective speech samples; and a comparator arranged to compare said first features extracted from a speech sample with second features extracted from one or more reference samples and to provide a measure of any differences between said first and second features for assessment of said user, wherein said reference samples are limited in bandwidth to the bandwidth of said sampled signals.

-
application software resident on a server and arranged to interact across a network with a user operating a client device to obtain one or more sample signals of the user'"'"'s speech; a datastore arranged to store said one or more user speech samples in association with details of the user; a feature extraction engine arranged to;
extract one or more first features from respective speech samples; and
extract one or more second features from one or more reference samples, said reference samples comprising a database of speech samples, wherein prior to operation of said feature extraction engine, said reference samples are distorted in a manner similar to any distortion involved in acquiring said sampled signals across said network; anda comparator arranged to compare said first features extracted from a speech sample with second features extracted from said reference samples and to provide a measure of any differences between said first and second features for assessment of said user.
