AWS has a service that turns text into speech called Polly. You can choose what type of voice, language and gender. AWS recently added a simple form, for an easy text to speech conversion and download. The form is limited to 3000 characters or less. The converted file is a MP3 format. For larger texts, the converted audio file will be stored in a S3 bucket for later retrieval. Using Amazon Polly along with Translate will be a cool experiment. AWS Translate is a natural language translation service.
