Patent ID: 8600065

Claim:
A non-transitory computer-readable storage medium having stored therein a breath detection program executable by a computer processor of a system having one or more computer processor for detecting for a sound inputted into a sound input device, the program causing at least one processor to perform operations, comprising: acquiring, from the sound input device, sound data representing a sound signal inputted into the sound input device; performing a first evaluation, using the one or more processor, of the sound signal represented by the sound data, by using a first criterion for detecting whether or not the sound inputted into the sound input device is a breath; performing a second evaluation, using the one or more processor, of the sound signal represented by the sound data, by using a second criterion which is different from the first criterion; and performing a breath detection, using the one or more processor, which detects that a breath is inputted into the sound input device when the first evaluation makes an affirmative evaluation in a first period in which whether or not a breath starts to be blown into the sound input device is determined, and which also detects that a breath is inputted into the sound input device when the second evaluation makes an affirmative evaluation in a second period in which whether or not a breath continues to be blown into the sound input device is determined, the second period being distinct from the first period.
