Technical point of view

• The challenge is to enable the Voice Portal to understand natural language rather than only single words

• Speaker verification is used in conjunction with Speech Recognition to increase the efficiency of the system and reduce misinterpretation

• To hide technical limitations the following techniques should be employed:

– use questions which are structured so that the possible responses of the users are limited to a certain number

– explain the user, that he is talking with a machine and not a live agent; then he will tend to speak slower and clearer

– use prerecorded audio as much as possible



Personalization

There are three main marketing issues, which are responsible fora successful Voice Portal integration of applications and content services:

Marketing point of view

NavigationService-portfolio



Serviceportfolio

• There are specific applications and content services that are especially appropriate for voice access

• Key Voice Portal opportunities lie in the telematics and mobility space

• In-car use will be a key segment for the usage of voice portal applications

• Criteria for using Voice to access specific services are:

– Hands-Free/Eyes-Free (Travel/Navigation services, PIM)

– Efficiency (Dictating emails, voice dialer, v-commerce)

– Enriching content (horoscopes, sports, music, cinema)

– Privacy/Security (v-commerce, banking, brokerage)



Note: erotic, flirt, fun applications (jingles,..) are generally underestimated because of the interview situation

Market Potential of Mobile Portals, October 2001 by TNS EMNID Telecommunication&IT.

Serviceportfolio



Serviceportfolio

• Most attractive content services are location based services and travel/traffic services; finance, news and weather have also a certain potential

• Personal Information Management (PIM) services including calendar, address book, email and unified messaging will be key applications

• These kind of personal communication services will be the driver for users to access also other services by voice



• Reasons for a low usage:

– People have to get used to Speech Recognition; in the first weeks

a lot of the callers did not say a word

– People are only interested in a few services so they also use only a limited amount of services

• An intuitive navigation is the key for a higher acceptance and usage

• Offer an easy service to increase your targetgroup and the calling activity

Navigation



• Content personalization enhances the user’s experience and creates sticky content which decreases the churn rate

• With personalization the handset is more than a pure communication device; it becomes a personal information device

• Allow the user to synchronize their central address bookvia voice, Web or WAP
