Telephone voice services for travelling professionals or for customer-service applications are becoming more and more popular. IVR (interactive voice response) is the current technology - and it works - but IVR systems require their own infrastructure and skill set, which can be difficult to justify when most enterprises must also support Web initiatives.
VoiceXML eases this problem because voice applications can reside on today's Web servers and be maintained by IT administrators. To round out a fully functioning voice platform, companies also need a VoiceXML interpreter. One such product is VoiceGenie Technologies's VoiceXML Gateway Version 4.5. It provides markup tags modelled after Web languages, and its VoiceXML Interpreter controls speech functions and the associated telephony equipment and speech engines.
Once a company places a VoiceXML application on its Web server, the VoiceGenie VoiceXML Gateway system answers phone calls, processes the voice commands, and delivers the spoken results back to the caller. The VoiceXML application and, say, the inventory database, can reside on the same Web server, simplifying a company's infrastructure. The standard design of the gateway means IT administrators don't have to worry about integrating disparate proprietary components to work with the VoiceXML application.
The only piece missing from this gateway solution is VoIP (voice over IP), which VoiceGenie included in Version 5.0, scheduled to ship early this month. Despite this shortcoming, VoiceGenie's gateway supports multiple speech engines, has a very strong VoiceXML 1.0-compliant interpreter, and is easy to implement, earning it four stars.
We tested VoiceGenie VoiceXML Gateway running SpeechWorks International's Speechify 1.1 TTS (text-to-speech) software and Nuance Communications' Nuance 7.0.4 speech recognition engine. With four TTS channels on a Pentium II CPU with 256MB of memory, the gateway responds quickly, taking less than one second to play back initial audio. This is especially good performance when you consider the large amount of memory and CPU resources that speech files generally consume.
For companies that don't want to make a hardware investment right away, VoiceGenie recently introduced GenieHosting.com, a cost-effective ASP (application service provider) service that offers all the features of the gateway.
A VoiceXML interpreter is one of the
most critical parts of
any VoiceXML solution because it must precisely execute VoiceXML commands. To evaluate VoiceGenie's interpreter, we used a stock-quote lookup and a read-back application to test the majority of VoiceXML's 47 tags and 187 attributes. Some of these specifications can be very difficult to implement, but the VoiceGenie VoiceXML interpreter properly handled each tag and attribute. VoiceGenie plans to update its interpreter to meet VoiceXML 2.0 standards once the 2.0 specifications are finalised.
The open design of this product is another strength. The SpeechWorks and Nuance software plug-ins delivered exceptional TTS and speech recognition, provided clear read-back of our text, and hardly ever misunderstood our spoken input. You can also choose to install other engines, such as the AT&T Watson TTS module.
VoiceGenie VoiceXML Gateway allows a company to reuse its existing Web infrastructure. Organisations can also move away from proprietary IVR systems and their prohibitive setup and development costs. The flexibility that VoiceXML provides in personalising Web content delivered via wired and wireless devices offers companies a competitive advantage today that employees, partners, and customers will expect in the near future.

Oh my stars!
VoiceGenie VoiceXML Gateway 4.5 will also be the last product review to be rated according to a series of stars. The star system will be replaced with a new three-tiered rating consisting of: Deploy, Consider, Reject. Unlike the stars, the new rating is designed to be a clear call to action rather than an arbitrary constellation. After all heavenly bodies are pleasant to look at when they are billions of miles away, but don't really say much about software and hardware solutions.
