Hello, I create one WAV file that has: Question + Option 1 + Option 2 + Option 3 + . I noticed towards end of the file Cepstral Allison starts chopping and speeding up. So my question text that gets converted to WAV file using swift EXE looks like: <break strength='weak'/>Which is the biggest mammal on land? <break strength='weak'/>Select one of the following choices.<break strength='weak'/>Or press star to skip the question <break strength='weak'/>1 <break strength='weak'/> Parrot <break strength='weak'/> 2 <break strength='weak'/> Elephant <break strength='weak'/> 3 <break strength='weak'/> T-Rex <break strength='weak'/> 4 <break strength='weak'/> Blue Whale <break strength='weak'/> And my csharp code looks like: pStrRetID = mObjMainSession.PlayAndGetDigits(1, 1, 3, 5000, "*#", @"C:\FreeSWITCH\sounds\en\us\chAsmt\Student_1222\Q1.WAV ", @"C:\FreeSWITCH\sounds\en\us\chAsmt\static\error\invalid_choice.wav", "^\\d", ""); What happens is, the voice just starts chopping and speeding up between options. Even though I am not able to say that it only does that towards the end, I think so. I thought, if I break each file into individual WAV instead of 1 big WAV, it may help? Is there a way to play multiple (separate) WAV files in PlayAndGetDigits function? Please help. Malay Thakershi
