Benefits - Amazon Polly

Some of the benefits of using Amazon Polly include:

  • High quality – Amazon Polly offers highly-performant generative, long-form, neural, and high-quality text-to-speech (TTS) voices. These technologies synthesize natural speech with high pronunciation accuracy (including abbreviations, acronym expansions, date/time interpretations, and homograph disambiguation).

  • Low latency – Amazon Polly achieves fast responses, which makes it a viable option for low-latency use cases such as dialogue systems.

  • Support for a large portfolio of languages and voices – Amazon Polly supports dozens of voices and languages, offering male and female voice options for most languages. This number will continue to increase as we bring more neural voices online. US English voices Matthew and Joanna can also use the Neural Newscaster speaking style, similar to what you might hear from a professional news anchor.

  • Cost-effective – Amazon Polly's pay-per-use model means that there are no setup costs. Start small and scale up as your application grows.

  • Cloud-based solution – On-device TTS solutions require significant computing resources, notably CPU power, RAM, and disk space. These can result in higher development costs and higher power consumption on devices such as tablets, smartphones, and so on. In contrast, TTS conversion done in the AWS Cloud dramatically reduces local resource requirements. This enables support of all the available languages and voices with outstanding quality. Moreover, speech improvements are instantly available to all end users and don't require additional updates for devices.
