Abstract
Abstract A method for generating connected word templates begins with generating isolated word templates of selected words. The isolated word templates are used to extract a continuous word template from a segment of continuous speech containing the selectd words. Both the isolated word templates and the connected word templates can be used to generate speech to determine the quality of the generated templates through aural judgment.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
63 words
A method for generating a template for recognition of connected speech, comprising the steps of: (a) generating an isolated word template of a selected word; (b) identifying the selected word from a stream of continuous speech by matching the continuous speech with the isolated word template; and (c) extracting a continuous word template from the continuous speech which corresponds to the selected word.
Claim 2
Independent Claim
63 words
A method for generating a template for recognition of connected speech, comprising the steps of: (a) generating an isolated word template of a selected word; (b) identifying the selected word from a stream of continuous speech by matching the continuous speech with the isolated word template; and (c) extracting a continuous word template from the continuous speech which corresponds to the selected word.
Claim 3
Dependent Claim
19 words
The method of claim 1, further comprising the step of: (d) before step (b), compressing the isolated word template.
Claim 4
Dependent Claim
40 words
The method of claim 1, further comprising the steps of: (e) after step (a), generating speech from the isolated word template; (f) listening to the generated speech; and (g) if the generated speech is not suitable, returning to step (a).
Claim 5
Dependent Claim
40 words
The method of claim 1, further comprising the steps of: (h) after step (c), generating speech from the connected word template; (i) listening to the generated speech; and (j) if the generated speech is not suitable, returning to step (a).
Claim 6
Independent Claim
115 words
A method for generating a template for recognition of connected speech, comprising the steps of: (a) creating an isolated speech template of a selected utterance; (b) generating an utterance from the isolated speech template, listening to the generated speech, and returning to step (a) if the isolated speech template is insufficient; (c) compressing the isolated speech template; (d) identifying the selected utterance from a stream of continuous speech by matching the continuous speech with the isolated speech template; (e) generating an utterance from the connected speech template, listening to the generated speech, and returning to step (d) if the connected speech template is insufficient; and (f) retaining the connected speech template as the generated template.
Claim 7
Independent Claim
115 words
A method for generating a template for recognition of connected speech, comprising the steps of: (a) creating an isolated speech template of a selected utterance; (b) generating an utterance from the isolated speech template, listening to the generated speech, and returning to step (a) if the isolated speech template is insufficient; (c) compressing the isolated speech template; (d) identifying the selected utterance from a stream of continuous speech by matching the continuous speech with the isolated speech template; (e) generating an utterance from the connected speech template, listening to the generated speech, and returning to step (d) if the connected speech template is insufficient; and (f) retaining the connected speech template as the generated template.
Claim 8
Independent Claim
92 words
A method for creating a template for recognition of connected speech, comprising the steps of: (a) determining the endpoints of a selected isolated word; (b) generating the selected word to detect the accuracy of endpoint detection; (c) if the endpoints are not sufficiently accurate, returning to step (a); (d) matching a continuous utterance with an isolated template of the selected word to determine connected word endpoints; (e) generating the selected connected word to detect the accuracy of endpoint detection; and (f) if the endpoints are sufficiently accurate, saving the connected word template.
Claim 9
Independent Claim
92 words
A method for creating a template for recognition of connected speech, comprising the steps of: (a) determining the endpoints of a selected isolated word; (b) generating the selected word to detect the accuracy of endpoint detection; (c) if the endpoints are not sufficiently accurate, returning to step (a); (d) matching a continuous utterance with an isolated template of the selected word to determine connected word endpoints; (e) generating the selected connected word to detect the accuracy of endpoint detection; and (f) if the endpoints are sufficiently accurate, saving the connected word template.
Claim 10
Dependent Claim
18 words
The method of claim 6, wherein steps (b) and (e) include detecting the quality of the selected word.
