Hello I encountered the same problem with a different voice API wit.ai, I solved the problem by setting params=( open("/home/pi/Downloads/sample.wav") )
sample code below

import subprocess, os, sys, unirest, time
print ("Recording")
#a1 = "arecord -d 2 -D plughw:1,0 -r 16000 -f S16_LE sample.wav"
#subprocess.call(a1,shell= True)
print ("Done")

response = unirest.post("https://api.wit.ai/speech?v=20160526",
headers={
"Authorization": "Bearer JIAK5Q5KOHEBZEBREPDLVM3ILPGNJYFE",
"Content-Type": "audio/wav",
"Content-Length": "40000",
},
params=(

open("/home/pi/Downloads/sample.wav")
)
)
time.sleep(2)
print" ===========after sleep"
print str(response.code)
print"response.code"
print str(response.headers)
print" response.headers"
print str(response.body)
x = str(response.body)
print" response.body"
print str(response.raw_body)
