About pronunciation fine-tuning: The ReadSpeaker team accesses the content through our digital platform so that they can hear the issues with audio in context, then they apply the correction to Cengage’s library, and finally they return to the content to verify that the pronunciation has been applied properlyHaving a team that is readily available and easy to work with has been vital. ReadSpeaker’s support and technical resources have been extremely helpful in implementing this service into our program.” View customer story
