Two data scientists at Amazon have successfully created an Irish accent for the virtual assistant, Alexa, using artificial intelligence (AI) and text-to-speech technology. This breakthrough in AI-generated voices has opened up new possibilities in research, commercial, and personal settings.
The use of AI-generated voices has become increasingly popular, with users utilizing the technology. For instance, audiobooks are now being narrated by AI-generated human voices. Moreover, scammers are using AI voices to impersonate others and deceive people into giving them money. Advertisements are also incorporating AI-generated voiceovers to make the content more engaging and personalized.
Georgi Tinchev and Marius Cotescu, the two data scientists behind the development of an Irish accent for Alexa, described the Irish accent as “a hard one” to master. They employed a technique known as voice disentanglement, which involves pinpointing specific aspects of speech, such as tone and intonation. This technique was previously promoted by Amazon scientists to enhance diversity and inclusion in voice assistants.
To create an Irish English-speaking Alexa, the data scientists used an existing Alexa model with a British accent as a baseline. They trained the model on Irish accents generated by text-to-speech models and voice recordings. By analyzing these accents, they were able to identify the distinctive aspects of the Irish accent.
The scientists then modified certain sounds, such as emphasizing the “r” sounds, to make the voice sound more authentically Irish. This process condensed hours of language training with voice actors, thanks to AI’s ability to mimic regional dialects and accents across different languages.
The successful creation of an Irish accent for Alexa showcases the immense progress made in AI-generated voices. The technology has become so advanced that the generated voices sound eerily similar to human voices. This raises both opportunities and concerns regarding the potential misuse of AI-generated audio.
Moving forward, this breakthrough in creating regional accents for virtual assistants could pave the way for even more diverse and inclusive voice experiences. Users may soon be able to choose from a wide range of accents and dialects, making their interactions with virtual assistants more personalized and relatable.
Overall, the development of an Irish accent for Alexa demonstrates the power of AI and its impact on voice technology. As AI continues to advance, we can expect even more exciting developments in the field of text-to-speech, with AI-generated voices becoming indistinguishable from human voices.
