In addition to Standard TTS voices, Amazon Polly offers Neural Text-to-Speech (NTTS) voices that deliver advanced improvements in speech quality through a new machine learning approach. Polly’s Neural TTS technology also supports two speaking styles that allow you to better match the delivery style of the speaker to the application: a Newscaster reading style that is tailored to news narration use cases, and a Conversational speaking style that is ideal for two-way communication like telephony applications.
Finally, Amazon Polly Brand Voice can create a custom voice for your organization. This is a custom engagement where you will work with the Amazon Polly team to build an NTTS voice for the exclusive use of your organization.

| Senior Software Developer at a tech vendor with 10,001+ employees | 4.0 | I use Amazon Polly to convert text into speech, primarily for disabled users and IVR calls. Its multilingual capabilities and integration with AWS are valuable, but I wish it offered more natural speech and additional languages to enhance its utility. |

| Lead Engineer at HCLTech | 3.5 | I use Amazon Polly with AWS for text-to-speech in Amazon Connect, leveraging SSML tags for enhanced speech patterns. However, using multiple tags for conversational speech sometimes results in errors, which needs improvement. |
