22. The method as claimed in claim 21 , further comprising: determining the plurality of speech recognition failures for the speech data and outputting the check results for the plurality of speech recognition failures.
22. The method as claimed in claim 21 , further comprising: determining the plurality of speech recognition failures for the speech data and outputting the check results for the plurality of speech recognition failures. 23. The method as claimed in claim 22 , wherein determining the plurality of speech recognition failures comprises analyzing non-received packets for a received input speech signal to thereby calculate a channel transmission error value, and determining whether the input speech signal is compatible with speech recognition according to whether the channel transmission error value exceeds a predetermined transmission error reference value.
