I don't think either DTX or VAD should change the output size, only the input 
size (from the decoders perspective) will change. So, if you know you are 
sending 1/4 of a second of sound every time and you are using wide-band speex 
(16kHz) on 16bit sound data, that gives you 1/4 * 16000 * 2 = 8000 bytes of 
output data...
