Set up Amazon Polly
Amazon Polly
We highly recommend you to use Amazon Polly as Text-to-Speech service of your audiobooks because of its speech quality and cost-effectiveness. While this is not a free service, if you're first to use AWS, you're eligible to the AWS Free Tier which allows you to turn 5 million characters per month into speech for free for the first 12 months. There is almost no worry for those who make audiobooks for language learning to exceed this limit. Even if you're not, pay-as-you-go $4.00 per 1 million characters for speech requests is probably quite affordable. You barely use the amount of 200,000 characters per month.
