New – Lengthy-Type voices for Amazon Polly

We’re launching three new voices for Polly. Powered by a brand new long-form engine, the voices are pure and expressive, with acceptable pauses, emphasis, and tone.

New Voices
The brand new long-form voices are good for weblog posts, information articles, coaching movies, and advertising and marketing content material. The underlying Machine Studying mannequin extracts that means from the textual content, studying about speech segments, prosody (the sample of rhythm and pauses), intonation, and different features of expressive speech, permitting the synthesized audio to specific feelings, particularly in dialogs. The brand new long-form engine makes use of a deep studying text-to-speech (TTS) mannequin skilled to accumulate a contextual understanding of the textual content that enables it to specific prosody in an acceptable means. This enables the intention of the story to drive the vocal efficiency and create the right emphasis, pauses, and tones of a practical human voice.

Listed here are the brand new voices:

Utilizing the New Voices
You’ll be able to entry the brand new voices utilizing the AWS Administration Console, AWS Command Line Interface (AWS CLI), or the AWS SDKs. Utilizing the CLI, I begin by itemizing the voices that use the brand new long-form engine:

$ aws --region us-east-1 polly describe-voices --output json 
  | jq -r '.Voices[] | choose(.SupportedEngines | index("long-form")) | .Identify'
Danielle
Gregory
Ruth

I can decide one, or I can attempt all of them:

for v in `aws polly describe-voices --output json 
          | jq -r '.Voices[] | choose(.SupportedEngines | index("long-form")) | .Identify'`; do
    Textual content="Whats up my identify is $v and I can learn weblog posts, articles, 
and different long-form content material for you. I'm the most effective!"
    aws polly synthesize-speech --output-format 'mp3' 
    --text "$Textual content" --voice-id $v $v.mp3 --engine long-form; 
    aws s3 cp $v.mp3 s3://jbarr-voices; 
executed

My shell script had a small quoting bug, however the ensuing audio was too humorous to not embrace!

Programmatically, you may reproduce my instance by writing code that calls the DescribeVoices and SynthesizeSpeech features.
