Benefits

Amazon Polly provides dozens of languages and a wide selection of natural-sounding male and female voices. Amazon Polly's fluid pronunciation of text enables you to deliver high-quality voice output for a global audience.

Modify Amazon Polly voices to best suit your needs – Amazon Polly supports lexicons and SSML tags which enable you to control aspects of speech, such as pronunciation, volume, pitch, speed rate, etc.

Amazon Polly allows for unlimited replays of generated speech without any additional fees. You can create speech files in standard formats like MP3 and OGG, and serve them from the cloud or locally with apps or devices for offline playback.

Delivering lifelike voices and conversational user experiences requires consistently fast response times. When you send text to Amazon Polly’s API, it returns the audio to your application as a stream so you can play the voices immediately.

Amazon Polly’s pay-as-you-go pricing, low cost per character converted, and unlimited replays make it a cost-effective way to voice your applications.

Use Cases

Content Creation

Audio can be used as a complementary media to written and/or visual communication. By voicing your content, you can provide your audience with an alternative way to consume information and meet the needs of a larger pool of readers. Amazon Polly can generate speech in dozens of languages, making it easy to add speech to applications with a global audience, such as RSS feeds, websites, or videos.

E-Learning

Amazon Polly enables developers to provide their applications with an enhanced visual experience such as speech-synchronized facial animation or karaoke-style word highlighting. Amazon Polly makes it easy to request an additional stream of metadata with information about when particular sentences, words and sounds are being pronounced. Using this metadata stream alongside the synthesized speech audio stream, customers can animate avatars and highlight text as it is currently spoken text in their app.

Telephony

Missing alt text value

With Amazon Polly, your contact centers can engage customers with natural sounding voices. You can cache and replay Amazon Polly’s speech output to prompt callers through interactive voice response (IVR) systems, such as Amazon Connect. Additionally, you can leverage Amazon Polly’s API to deliver automated real-time information such as service status, account and billing inquiries, addresses, and contact information.
