I tried to play the audio on Alexa skill from my S3 Bucket, from the test tab, **it show but in fact, I can't hear any sound
19 avril 2022, par Siti MaynaSo I tried to play the audio on Alexa skill from my S3 Bucket, from the test tab, it show but in fact, I can't hear any sound. Another fact is, that I tried to use the sample audio from https://developer.amazon.com/en-US/docs/alexa/custom-skills/ask-soundlibrary.html and it is worked, but why it won't work when it comes from my own S3 Bucket ?


Notes :


I've tried to test the skill using my mobile phone also.


I've tried to encode the audio using FFmpeg.


I've tried to use Jovo to convert the audio. https://v3.jovo.tech/audio-converter


I don't know how to fix this error.


There is no error message on cloud watch.


Assumptions :
There is some problem related to the audio resources or there is more set to play audio from S3 Bucket since the sample audio is working.


Steps to reproduce :




Build the interaction model






Encode the audio to make it Alexa skill friendly (fulfill the requirements, like sample rate, etc), I used and tried all of these :




A :


ffmpeg -i -ac 2 -codec:a libmp3lame -b:a 48k -ar 16000 -write_xing 0 


B :


ffmpeg -i -ac 2 -codec:a libmp3lame -b:a 48k -ar 24000 -write_xing 0 


C :


ffmpeg -y -i input.mp3 -ar 16000 -ab 48k -codec:a libmp3lame -ac 1 output.mp3




Upload the audio resources on S3Bucket
Audio sample on s3 storage but none of them are produce any sounds






Use the link and insert it to APLA.json

 }
 ]
 }
 }



notes : I change the link sources based on audio that I tried.




the intent on lambda_function.py :




def _load_apl_document(file_path):
 # type: (str) -> Dict[str, Any]
 """Load the apl json document at the path into a dict object."""
 with open(file_path) as f:
 return json.load(f)

class LaunchRequestHandler(AbstractRequestHandler):
 """Handler for Skill Launch."""
 def can_handle(self, handler_input):
 # type: (HandlerInput) -> bool

 return ask_utils.is_request_type("LaunchRequest")(handler_input)

 def handle(self, handler_input):
 # type: (HandlerInput) -> Response
 logger.info("In LaunchRequestHandler")

 # type: (HandlerInput) -> Response
 speak_output = "Hello World!"
 # .ask("add a reprompt if you want to keep the session open for the user to respond")

 return (

 #.speak(speak_output)
 .add_directive(
 RenderDocumentDirective(
 token="pagerToken",
 document=_load_apl_document("APLA.json"),
 datasources={}
 )
 )

 )




Deploy






Test it
