Lipstream Brings Real-Time Voice Services to Cultura Inglesa Online Language Courses

April 20, 2001

Cupertino, Calif. — Lipstream® Networks, Inc., the leading provider of real-time voice over the Internet for business, today announced that its VoIP services have been integrated with the Cultura Inglesa Online (www.culturainglesaonline.com) language education portal. The addition of Lipstream’s voice services enhance Cultura Inglesa Online’s Internet-based courses with a complete, real-time voice solution that delivers a highly interactive human experience for connecting online class participants with instructors and each other.

Lipstream’s PC-to-PC voice service enables Cultura Inglesa Online’s language instructors and students to engage in group discussions, one-on-one conversations, and send text messages in real-time, enhancing student comprehension and retention, and allowing for written language practice and spoken language pronunciation feedback.

“Cultura Inglesa Online has always provided valuable online language learning services such as writing, listening and reading exercises,” said Roberto Beck, CEO at Cultura Inglesa Online. “However, conversation is crucial to the correct learning of a spoken language. With the addition of Lipstream’s advanced VoIP services, we’re now able to offer students and teachers a real-time speaking service, and a complete, cutting-edge online education solution.”

“Effective communication is essential to the learning process and is especially important to an online language education scenario, such as Cultura Inglesa Online’s,” said Matt Jones, President and CEO at Lipstream. “By adding our live voice services to its Web-based language courses, Cultura Inglesa Online is bringing the immediacy and effectiveness of online voice interaction to the virtual classroom.”

Lipstream’s Real-Time Voice Service in the Virtual Classroom

Lipstream’s real-time voice service is an ideal online tool for distance learning environments. Lipstream’s VoIP services run over the Lipstream Network, which is based on a unique architecture providing a high quality, secure, highly scalable medium for the transmission of real-time communications. Unlike other VoIP vendors, Lipstream’s network features multiple redundancy and rapid problem correction to ensure the best available voice quality for every connection. Lipstream’s flexible termination options of connecting to PC’s, a local phone number, toll free (800) number, or on premise voice gateway enable businesses to choose the service that best meets their infrastructure and cost needs.

In virtual classroom environments, Lipstream allows students and instructors to conduct voice discussions with a single click. Participants can talk from PC-to-PC, or PC-to- phone anywhere in the world where Internet access is available. With Lipstream’s voice services, students and teachers can converse naturally, just as they would in a real classroom. The results are greater comprehension and more effective learning. Students can send text messages and research the Web while they are attending a training session, and training conferences can be recorded and saved for review at a later time. Educators can combine online course content with real-time voice instruction so that students can ask questions as they arise and obtain answers immediately. As more students are enrolled, Lipstream makes it easy to add more users.

Lipstream’s voice service is now available with Cultura Inglesa Online’s language education portal. Other Lipstream customers in the online education space include EF Education and Global English.
