Amazon’s has proprietary software for almost every use case. An example is the text to speech market, which has at least 2 options.
In this article, you’ll learn how to use text to speech on Amazon using its 2 solutions: Polly and Alexa.
What is Amazon Polly?
Amazon Polly is the company’s lifelike speech generator. As with Google’s technology, there are 2 main levels:
- Standard TTS, which uses AI and deep learning to synthesize realistic voices in a range of languages
- Neural TTS, which uses further machine learning techniques to improve tone and reading quality.
One example of the Neural text to speech improvement is its newscaster voice. As the name suggests, it reads text in the style of a newscaster. This includes tone, flow, and emphasis.
Which Languages does Amazon Polly support?
Polly supports 22 languages. Within these are different accents and dictionaries. For example, English includes:
- American English
- Canadian English
- British English
- Indian English
- South African English
- New Zealand English
- Welsh English
Although the list isn’t as large as some other Transkriptor alternatives , it covers all of the most popular worldwide languages.
What is the Pricing of Amazon polly?
Polly’s pricing is very similar to Google’s. The pay as you go service includes 1 million characters a month for $4, or $16 for the neural voices. You can pay for less, and prices can be as little as $0.01 per job.
How to Use Text to Speech with Amazon Polly?
Figuring out how to use text to speech on Amazon Polly isn’t difficult. The steps are as follows:
- Set up an AWS account if you don’t already have one.
- Log in to the Amazon Polly page.
- Paste your text into the text input box. You can do this as plain text or Synthesis Markup Language, which allows you to control aspects such as pitch, volume, and speech rate.
- Polly will generate an audio stream of the text.
- Next, choose the voice you want to read your text. It must be in the same language as the text (Polly doesn’t work as a translation service).
- Choose your output format and download the file.
Where Can Amazon Polly Be Used?
Once you know how to use text to speech on Amazon, it’s worth thinking about where you might use the audio files. Some examples include:
Learning
You can use Polly to read out lectures and teaching documents, or for other learning applications. For example, the foreign language app Duolingo uses Amazon Polly for its text-to-speech. Considering this is a situation where pronunciation is vital, it should highlight the quality of Polly’s text to speech service.
Content Creation
Text to speech is helpful for content creation. For example, you could use it to convert a blog post into a podcast or to create a voiceover for a YouTube video. It could also help with accessibility for visually impaired people by reading out website content.
Telephone Services
Contact centers have long used artificial voices for their telephone menus. The benefit of using a lifelike text to speech service is that people prefer to listen to realistic voices. Plus, the setup cost would be fairly low because there isn’t that much text in a telephone menu system.
Alexa is Amazon’s voice command service. It’s built into a range of devices, including smart speakers, TVs, smartphones, and more. There are a few options for how to use text to speech on Amazon Alexa, although none are as advanced as Polly.
How to Set Up Amazon Alexa Routines?

- Tap When This Happens and then Voice.
