Motivated by the widespread acclaim for Alexa, we aimed to embed the same caliber of voice technology within BotTalk, offering our users unparalleled quality in voice synthesis.

Shortly after integrating Amazon Polly, we observed firsthand the challenges faced when converting text to speech, particularly with the pronunciation of local German names and geographic locations. This insight led to the rapid development and implementation of a highly requested feature from our initial user feedback: Dictionaries. This feature empowered our users to customize pronunciations easily, providing a simple and intuitive user interface for enhancing speech accuracy.

The evolution of Amazon Polly since its announcement in 2016 has played a significant role in our continuous improvement. AWS introduced Polly as a managed service that revolutionized text-to-speech conversion, enabling the creation of speech-enabled applications and products without necessitating machine learning expertise. Just by calling an API, developers could leverage this service to enhance their applications. Over time, Polly expanded its voice options to include 29 languages and 59 different voices, demonstrating AWS's commitment to diversity and inclusivity in voice technologies.

Moreover, AWS's introduction of Neural Text-To-Speech (NTTS) and the newscaster style feature marked a pivotal advancement in speech synthesis. NTTS, through a novel machine learning approach, significantly enhances the naturalness and expressiveness of synthesized speech, bringing it ever closer to human-like quality. This improvement is available for 11 voices, including all 3 UK English voices (Amy, Emma, and Brian) and all 8 US English voices (Ivy, Joanna, Kendra, Kimberly, Salli, Joey, Justin, and Matthew), both in real-time and batch mode. The NTTS technology also introduced the capability to apply various styles to synthesized speech, further enriching the auditory experience.

With these advancements, BotTalk has been able to offer our users the ability to create audio content that not only resonates with a broad spectrum of listeners but also enhances their publishing capabilities.
