Interactive Voice Response (IVR) systems are essential for businesses looking to automate customer interactions. A professional and clear IVR prompt ensures that customers can navigate options effectively. If you already have a WAV file for your IVR prompts, you might need to convert it into a specific format compatible with your VoIP system or if you dont have wav files you can create using website Text to WAV converter  https://www.narakeet.com/create/text-to-wav.html .

In this article, we’ll guide you through creating and converting IVR prompt audio files using two online tools: g711.org and 3CX Audio Converter.
