Text has been converted to speech across multiple languages with customizable voice settings

The most beneficial aspect of Amazon Polly is its ability to convert text to speech in multiple languages. It allows us to change the voice configurations for both male and female voices, and enables adjustments in pronunciation and delays. These features help us effectively target our users. Additionally, the integration capabilities with AWS services like Lambda aid us in storing Polly voice messages in DynamoDB and S3. It also offers configurations in multiple languages, enhancing our service reach.

Facilitating seamless international communication through efficient transcription and translation tasks

The product is limited when it comes to integrating with different platforms and using many other APIs. The marketplace is very limited and it's difficult to implement solutions in it. Enhancing features by integrating with other AI solutions like Gemini and Menus, as well as improving communication across platforms, would make it a more comprehensive solution.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The most beneficial aspect of Amazon Polly is its ability to convert text to speech in multiple languages."

"The sound generated by Amazon Polly is very natural, and I appreciate the options to select different voices, including an expensive or cheaper one, and the Structured Speech Markup Language (SSML) feature allows me to specify if I want a warmer or higher tune, which has helped make the meditations sound very natural."

"We can use the SSML tags in Amazon Polly to modify text-to-speech by controlling speech patterns and behaviour."

"Amazon Polly offers significant features like the ability to select different voice categories and language options, such as Spanish, Portuguese, German, and French, which is particularly useful for maintaining worldwide contact centers and enhances customer experience by allowing us to give voice responses instead of text-based responses."

"They have the neural voices, and they're so realistic, you don't even know that a person is not reading to you, making things much better."

"Amazon Polly is useful because it's helpful to hear the words on top of it when I can't take in information in a general way. Sometimes, it's very taxing if I'm trying to read cases. They have the neural voices, and they're so realistic. You don't even know that a person is not reading to you, making things much better. I know that they do have the ability to provide you with your own lexicon that's personal to you. I like that you can adjust the pitch and the speed of the voice because some people talk way too fast. Or if you're reading, I read slowly, so that's always helpful. One of the functions that I find helpful is that when reading material on the web, it's like it has its own browser. You go to the URL, and you don't have to read the whole thing, and you can stick the cursor on the place where you want it to start. Then if you want it to skip over something, you put it somewhere else, and that's ideal for reading case law because you skip around a lot. You don't really read it from start to finish. It helps if someone's going to read all those citations because they definitely want to be able to skip that."

"Useful text-to-speech and speech-to-text features."

"Overall, in my opinion, the transcription service is rated as ten out of ten."

"The documentation and boilerplate code [a template of code] was available."

Cons

"The price could be better; I wish it weren't so expensive to do because it's really cool."

"Another point is that Amazon Polly needs better hard phone capability compared to Cisco solutions, which easily connect with hard phones."

"When you put more tags inside Amazon Polly to define break time and instruct the speech to be conversational, sometimes it gives you an error."

"To get to the solution, there are many steps to go through, such as setting up AWS, which is a lot of hops."

"The price could be better. I wish it weren't so expensive to do because it's really cool. I would love to see them have lexicon packages of them like, this is for lawyers, this is for accountants, and it's going to have a lot of things in it. I also think they could do a better job at showing use cases other than telemarketing or contact center stuff like bots that are very commercial. I know that's where the money is, but it's such a huge hole that's missing for people with disabilities that are even worse than mine. Some people cannot see or hear at all, but they're not just cognitively impaired."

"Amazon Polly's standard text-to-speech feature could be enhanced to deliver more natural and expressive human-like speech."

"Lacks a voice recording option."

"It can improve based on the native language."

"The product is limited when it comes to integrating with different platforms and using many other APIs."

Pricing and Cost Advice

"The price could be better. Neural voices are so realistic, and I want to say that they have it so that you can try to tell where the voice is coming from or something like that. But if I have more than one, it's so expensive to have to listen to a bunch of cases on my phone and have the neural voice read to me. It really wouldn't be worth it. It'd be paying probably more than what I make in the case. Right now, I'm on the free tier, and I think the number of minutes that you get is reasonable as long as you're not doing this all the time and you're using it judiciously. I have some credits that I think I can use, but I don't know how fast they'll go through."

"The solution has a pay-as-you-go pricing model, where you must pay according to your usage."
