Text-to-speech, is a technology that enables the conversion of text to audio, offering new possibilities for interaction and accessibility. Thanks to recent developments in next-generation speech synthesis, artificial voices have become increasingly realistic and natural. In this context, Amazon Polly stands out as one of the leading services in the field of speech synthesis. Let's find out the strengths of Amazon Polly and how XCALLY best integrates it.

What is speech synthesis

Speech synthesis is the technology of turning a written text into an artificial voice through automated processing. This innovation enables companies to provide automated voice service and support, offering customers immediate and interactive communication. The fields of application are many, from accessibility to voice assistants. In customer service, it allows the user experience to be enriched with natural and expressive voice responses.

Speech synthesis applied to customer care: improving customer experience with artificial voice

Through speech synthesis, companies can create interactive voice guides, personalized voice announcements, and pre-recorded responses that are played back through artificial voices. This allows a high volume of customer calls and inquiries to be handled efficiently, offering immediate and accurate responses.

The benefits of text-to-speech applied to customer care are many.

  • 24-hour support: First, it enables companies to provide 24/7 service, eliminating dependence on human operators and ensuring immediate response even outside business hours. This means that customers can get support at any time, improving customer satisfaction and loyalty.
  • Standardized responses: the use of speech synthesis allows for standardization of the responses provided, ensuring consistency and uniformity in the message conveyed to customers. This is especially important when it comes to providing crucial information such as opening hours, product instructions, return policies, and so on. The artificial voice ensures that information is conveyed clearly and consistently, avoiding ambiguity or misunderstanding.
  • Ability to personalize the customer experience: through the choice of different voices, tones, and pitches, companies can create a more welcoming experience that suits their brand. For example, a company targeting a young audience might opt for a lively and dynamic voice, while a more traditional company might prefer a professional and reassuring voice.
