VoiceAge’s expertise and proven track record in developing speech and audio codec technologies and implementations provide a solid foundation for insights on current and emerging market needs and solutions. We have collected some of these ideas in these series of papers that show how VoiceAge can help you take a leading position in today’s and tomorrow’s markets.

Voice over Internet Protocol (VoIP)

Enabling High-Quality Wideband Speech Across Networks asserts that pervasive digital communication systems are creating an opportunity to introduce the superior quality of wideband speech to usher in next-generation hi-fi telephony. Moreover, the seamless interoperability of the ITU, 3GPP and 3GPP2 wideband speech coding standards facilitates fixed–mobile convergence, enabling operators to offer high-quality speech efficiently across several networks.

Wideband Telephony – Enhancing VoIP for full service success describes how the wideband speech spectrum adds a new dimension of richness and presence to speech communications and explains the benefits of VoiceAge wideband speech codecs – selected and recommended as standards by the ITU, 3GPP, 3GPP2 and CableLabs – for delivering speech with unmatched quality and robustness while ensuring transcoder-free interoperability across all networks.

Enabling High-Quality Speech over Converged Wi-Fi/Mobile Networks explains how operators can eliminate the impairments, costs and delays introduced by transcoding and provide improved speech quality by adopting the mandatory mobile codec standards AMR and AMR-WB in the converged Wi-Fi/mobile phones used in their solution implementations.

Wideband Speech Coding Standards and Applications is a technical paper that presents a summary of wideband speech coding standards for wideband telephony applications, with special emphasis on the AMR-WB standard recently selected by 3GPP and ITU-T. The quality advantages and applications of wideband speech coding, including telephony over packet networks, are also discussed.

Mobile Multimedia

Enhanced Speech and Audio Coding Technologies Enable Innovative Mobile Multimedia Services, originally published in Information Quarterly, Vol. 4, No. 1, 2005, describes some of the multimedia services supported on evolving mobile networks and explains the applicability of the hybrid AMR-WB+ speech and audio codec for enabling high-quality sound and robust service delivery.

Delivering Multimedia Content on Next-Generation Networks explains how highly efficient AMR-WB+ audio compression enables operators to deliver innovative multimedia services to more users by maximizing their utilization of network resources.

Next generation services NOW . . . with the latest hi-fi compression technology describes the latest standardized speech and audio compression technology capable of very low bit rates and introduces some of the innovative services that deliver hi-fi telephony and multimedia audio content.

The hi-fi audio codec designed for multimedia services and applications shows that most mobile multimedia applications combine both speech and other audio content, so a hi-fi codec that delivers consistently excellent quality for all audio types provides the best end-user experience.

AMR-WB+ Low complexity hi-fi audio for portable multimedia highlights the importance of keeping demands on mobile device CPU low to allow mainstream devices to run mobile multimedia and to extend the periods between battery rechargings so the services are available when and where users want them.

AMR-WB+ for more programs to more customers on more networks with more quality explains how multimedia broadcast, streaming and podcast applications benefit from the versatility, high quality, great bandwidth efficiency and low complexity of the AMR-WB+ speech and audio codec.

Consumer Electronics

Adding speech or audio to consumer electronics explains that each application type has unique requirements and constraints, and VoiceAge can work with application developers to deliver the best combination of codec attributes for the job.

Adding speech or audio to the networked home focuss on codec requirements for networked home applications.
