Atel: Speech-Enabled Computer-Telephony System

Atel is the first computer-telephony (CT) system in Persian which not only supports all features of the classical CT systems (Touch-Tone based), but also has intelligent speech processing capabilities. Today, telephones and automated telephony systems are inseparable parts of any organization or company. This system provides remote services to customers with minimal equipment and costs. Today, most automated telephony systems use touch-tone buttons as the user input device. In touch-tone CT systems, a tree structure is designed to provide information and ask for inputs from the user in different levels. Instructions have to be read for the user and their key inputs have to be defined. This has to be done at different levels to take the user to the desired destination. This means longer calling times and user dissatisfaction due to repetitive listening and unavoidable waiting. There are serious constraints on the number of choices the user may have in each branch of the menu tree. The speech recognition capability facilitates the clients inputs while reducing the complexity of the menu tree and reducing the call time significantly.


Atel is the first computer-telephony system in Persian, which in addition to supporting classical IVR systems (Touch-Tone based), supports intelligent features including automatic speech recognition, text to speech (text reader), speaker identification on voice and searching in telephony speech. In addition to facilitation of the relationship between clients and telephony systems, intelligent speech capabilities reduces costs and provides better services to customers.

  • The user can use automatic speech recognition to say the commands instead of pressing keys. It enables the system to avoid long menu readings and lets the user to use a natural way to enter the inputs.
  • With the help of text-to-speech (text reader), Atel is able to convert any text into speech leading to high flexibility in changing the messages played by the system instead of pre-recorded voices. This means significant cost reduction in developing customized IVR systems.
  • Using speaker recognition (identification/verification) enables Atel to recognize the caller by his/her voice. This capability can be utilized as a biometric to identify caller and to enhance security (e.g., in telephone banks). People always carry their voices and it cannot be lost or forgotten as in passwords or PINs.
  • By deploying word spotting in telephony speech in Atel, the system can be made sensitive to certain words. If specified words are said, the telephony system will do a pre-defined reaction.


Examples of Atel application: speech-enabled telephone-bank

Today, telephony systems are integral parts of e-banking and provide many banking services to clients. Utilizing speech recognition technology in these systems will renovate their performance. These systems not only facilitate and accelerate the connection of clients with banks but also are more attractive and pleasant for them. With Atel, the user can say a sentence to the system that contains a multi-level request.


For example, the phrase like “I would like you to fax my bill to the current telephone number” is equivalent to a three-level tree structure. Today, speech recognition technology in telephone banks is being used for English language banks such as Fidelity Bank, Columbia Bank and ABN Amro. For the Persian language, this is done for the first time by Atel.
