I am getting this error on passing a wav file into readwave function.

I originally had the same issue @PranavPable was experiencing (below), and I figured out a solution that I thought I'd document. To make the writeWave output compatible with gl_speech, just set the parameter extensible equal to FALSE.

#Doesn't work:
readWave("foo.wav")) %>%
  writeWave("bar.wav") #by default extensible = TRUE
gl_speech("bar.wav", sampleRateHertz = 8000L)
# 2019-12-07 22:29:51> Request Status Code: 400
# Error: API returned: WAV header indicates an unsupported format.

#Works:
readWave("foo.wav")) %>%
  writeWave("bar.wav", extensible = FALSE)
gl_speech("bar.wav", sampleRateHertz = 8000L)

Thanks, I'll keep this open so I can document it at some point :)
