Method Details

getSynthesizeSpeechUrl(params = {}, [expires = 3600], [callback]) ⇒ string?


You must ensure that you have static or previously resolved credentials if you call this method synchronously (with no callback), otherwise it may not properly sign the request. If you cannot guarantee this (you are using an asynchronous credential provider, i.e., EC2 IAM roles), you should always call this method with an asynchronous callback.

Generate a presigned url for AWS.Polly.synthesizeSpeech().


  • params (map) (defaults to: {})

    parameters to pass to the operation. See the AWS.Polly.synthesizeSpeech() operation for the expected operation parameters.

  • expires (Integer)

    (3600) the number of seconds to expire the pre-signed URL operation in. Defaults to 1 hour.

Callback (callback):

  • function(err, url) { ... }

    If a callback is supplied, it is called when a signed URL has been generated.


    • err (Error)

      the error object returned from the presigner.

    • url (String)

      the signed URL.


  • (string)

    if called synchronously (with no callback), returns the signed URL.

  • (null)

    nothing is returned if a callback is provided.
