HD Voice from GIPS customer Nimbuzz

  1. 1. A Light Reading Webinar The Potential of HD Voice (Wideband) HD-Voice Tuesday May 5, 2009 Hosted by Simon Sherrington Independent Consultant On Behalf of Light Reading Spo so ed by: Sponsored by p Guest speakers: Jeff Pulver - Entrepreneur Tobias Kemper - Nimbuzz
  2. 2. Speakers p Jeff Pulver – Serial Entrepreneur Joyce Kim - Chief Marketing Officer Global IP Solutions Jan Linden - VP Engineering Global IP Solutions Tobias Kemper – Head of Communications Nimbuzz
  3. 3. Agenda • Market Overview and Evolution of HD-Voice • The Importance of HD-Voice/Wideband in Voice Communications and Collaboration • The Technical Challenges of Achieving HD-Voice • Mobile HD Voice • Q&A
  4. 4. What is HD-Voice? •HD-Voice is : •Immersive experience, Life-like and natural •High quality, high fidelity audio user experience •Minimizes phone fatigue Wideband Has a New Name: HD-voice HD voice
  5. 5. Q&A with Jeff Pulver •Why does HD represents such an important development for y p p p the VoIP and larger telecom industries? •HDTV is well k HDTV i ll known b what signs d you see of momentum but h i do f building for HD in telecom? •How do you see developments playing out regarding HD in telecom? What should we look for as key milestones?
  6. 6. Poll question 1 q •What has been your experience with HD-Voice? •A) Never tried it •B) Have tried i once or twice B) H i d it i •C) Use it all the time or whenever I can ) •D) Not sure if I’ve tried it
  7. 7. Joyce Kim y Chief Marketing Officer Global IP Solutions
  8. 8. How do we Define HD-Voice? • Also known as “wideband” − Generally accepted technical definition: 7 kHz audio and above • Extends bandwidth beyond what is available in traditional telephony (PSTN) • Results in greater intelligibility − Fricative sounds (e g s and f) and heavy accents (e.g., • Sounds more natural – “life like experience” • Allows for greater user comfort and less fatigue
  9. 9. The HD-Voice Difference •IP networks present opportunity to use more audio spectrum − Better than PSTN quality is achievable in VoIP •Hardware, microphones, speakers can impact quality but limited signal bandwidth is the main quality factor Quality Visit http://gipscorp.com/wp to hear examples CD ‐Audio GIPS Wideband Speech Std Wideband Speech (e.g. G.722.2) GIPS Narrowband Speech Std Narrowband Speech  Implementation (PSTN) 200 ‐ 3400 Hz Frequency 3,4 4 kHz 6.4‐7.0 kHz 8 kHz 22.1 kHz
  10. 10. Why HD Voice/Wideband? •Well suited for multimedia, conferencing, distance learning, gaming, music •Differentiating factor •Softphone users get exposed to wideband and have raised the expectations •Increased market demand • Growing installed base of IP only applications such as soft phones, Wi-Fi/dual-mode phones, HW IP phones, conferencing applications •Enables new market opportunities & features
  11. 11. HD Voice is Essential to Overall Experience •Sound quality has a much greater impact on user experience when adding visuals like video p g − Telepresence and High Quality Desktop Video Conferencing
  12. 12. The HD-Voice Market – Multiple Market Forces Co Coming Together g oget e • Worldwide installed base of UC-capable and complete UC client base expected to grow from 29.3 Million in 2008 growing to 211.2 Million in 2014 (Frost & Sullivan) CSP-based Videoconferencing Market: Revenue Forecasts (North America) $600 16 14 $500 12 venue ($ millions) ) venue Growth (%) ) $400 10 $300 8 6 $200 Rev Rev 4 $100 2 $0 0 2007 2008 2009 2010 2011 2012 2013 2014
  13. 13. Codec Comparison MUSHRA test results for different codecs 100 90 80 70 60 50 40 30 20 10 0
  14. 14. A Good Illustration of HD-Voice Benefits • Ability to distinguish between speakers incredibly important • Long conference calls require more attention, as callers get fatigued more easily E A • Video conferencing requires HD-Voice to compliment the experience D • Intelligent server technology can support both g gy pp traditional telephony and HD-Voice B C • Traditional phone participants will hear everything in narrowband – lower quality • HD-Voice participants hear others in narrowband or high definition
  15. 15. Why Bandwidth Estimation is Important • When properly utilized, bandwidth estimation can ensure consistent, high quality experience − Fixed bit rate solutions estimate bandwidth once at the beginning of the call (or not at all) – no flexibility − Variable bit rate HD codecs adapt to the network 1) Fixed Codec Detects Bandwidth 2) Then Determines Bit Rate 3) Begins Sending Media 32 kbps? 32 kbps it is! …but bottleneck appearance during the call can cause delays if bit rate is not adjusted
  16. 16. Jan Linden VP of Engineering Global IP Solutions
  17. 17. Codec Design Considerations • Speech Quality • Complexity • Bit-rate Quality • Device issues Delay D l • Packet Loss • Processing • Delay Power • Ease of Use • Echo • Network • Audio Environment Bandwidth
  18. 18. HD-Voice Codec Selection •Not one codec fits all scenarios •Packet loss robustness important for VoIP •Variable bit rate attractive for IP networks − Automatic adaption to available rate attractive p •Packet overhead significant (5 – 32 kb/s) − Makes low bit rate codecs less attractive •Low delay very important •Standard versus proprietary − Standards usually come at a higher cost •Complexity an important issue in Mobile VoIP
  19. 19. Advancements in Speech Processing Design More Than Just a Codec Hardware Issues Speech Codec Codec (Processor, OS, Acoustics, etc.) Network Hardware Coping with Network Degredation Power Consumption VoIP Design Challenges Power Echo Echo Cancellation Environment – Additional Voice Background Noise, Processing Components Voice Environment Room Acoustics, etc.
  20. 20. Example of Challenges – Echo Cancellation p g •High delay in VoIP makes echo problem more prominent •Acoustic echo cancellation A ti h ll ti • Handsfree/speakerphone • Small mobile devices •Challenges in HD-Voice scenarios • More processing power required • More background noise picked up due to the extended audio band
  21. 21. Mobile Leading HD-Voice? •HD-Voice in cellular •Standards exist •Very limited deployment •Mobile VoIP •HD-Voice prevalent •iPhone VoIP phenomenon •High quality, easy to use applications •VoIP calling, IM, Messaging Nimbuzz is Pioneering the Way
