Hello, Voximal !

The virtual agent by phone


Call your Voximal, it speaks to you and understands your voice to dialog with you. It can also propose you more conventional menus using the keys on your phone. It answers the phone for you, to give you access to information, to collect datas or qualify, filter, transfer calls.

Easy to install : in your environment with a self-installing package, or in the cloud using the images available from many suppliers.

Modular: It’s ready for small installations to treat a few calls, and obviously, redundant configurations with many concurrent calls.

Programmable: It uses the standard VoiceXML or AIML programing languages. It can connect to your Chatbot to give it a phone call access.

It’s easy !

The Voximal solution is available as a free evaluation version. Take advantage of this offer to learn and create your services with VoiceXML language, or simply connect it to your Chatbot (watson, api.ai, pandorabot, davi, clustaar, …).

1Voximal is easy to install on a cloud server of your choice, a hosted server or a dedicated local server. Many virtual images or an auto installable package makes this simple  . It can also completed an Asterisk installation or FreePBX too.

You need to connect your Voximal to the telephone network with a VoIP account available from many operators. Meanwhile, you can use our shared phone numbers to access to your Voximal using an PIN access code (get it from your web administration interface).

You need then to configure or develop your call processing application using the VoiceXML standard language. A VoiceXML / PHP code editor is integrated and a lot of examples are provided. For natural language using, you need to connect your Voximal to your Chatbot. By this way you can have a phone call access. A lot of script are available in our GitHub.

Voximal is a standardized voice server with extended functionality: built-in speech synthesis, speech recognition, natural language, call campaign generator, call recording, conferencing, video, and more…

  • Linux / Asterisk 1.6 à 14
  • VoiceXML V2.1 (extra features)

Integrated Chatbots

The AIML (Artificial Intelligence Markup Language) is a XML language dedicated to managing a conversation/dialog.

<?xml version=”1.0″?>
<aiml version="2.0">
    <template>Hello Voximal !</template>

Voximal can change its voice and language, thanks to the synthesized voice. You choose to use remote resources over the Internet or a local one. They can be free of charge, or commercial with a better quality.

Integrated On-premise Synthesis Voices (MRCP/HTTP)

Voximal also supports speech recognition. You can talk to him naturally without using the keys on your phone. This allows you to create phone services in natural language, making it easier to interact with users. No more menus “to … press 1”, but use “Say … for …” or simply ask “How can I help you?”.
