Reconocimiento de voz

[roberkas98]

Buenas, el caso es que ando intentando crear una especie de reproductor de musica con reconocimiento por voz, al principio pense en sphinx pero luego me encontre pygsr(la api de google para su reconocimiento de voz) , y aunque era mas lenta, es muy sencilla.Ahora bien, con lo sencillo que es el codigo me da error.Agradezco cualquier ayuda ya que en google no he encontrado nada!

codigo:

Código Python:

from pygsr import Pygsr
speech = Pygsr()
speech.record(3) # duration in seconds (3)
phrase, complete_response = speech.speech_to_text('es_ES') # select the language
print phrase
 

Código Python:
