Introduction to personalised voice notification services

A personalized voice notification service generates audio versions of written messages using text-to-speech (TTS) technology. By using this technology, you can create custom audio notifications tailored to everyone. As a result, users can receive audio prompts that are more personalized and engaging, enhancing customer loyalty and experience.

Benefits of using a personalized voice notification service

Customer engagement, improved customer experience, and the ability to provide timely and accurate information are some of the benefits that can be realized. As customers feel appreciated and recognized, a personalized voice message can enhance the customer experience and create a more engaging and welcoming environment.

Understanding of personalised voice prompts

A personalized voice prompt is an audio message that is customized by using Text-To-Speech to address the user by name or provide specific information based on their profile or history. Some common types of personalised voice prompts are name, profile, context, location, activity, preference, and mood.

For example, the prompt for the name attribute could be “Hi [name], this is a reminder about your appointment tomorrow,” while the value for the appointment time attribute could be “Your appointment is at [time] on [date].”
