We’re back! It was a bumpy ride, but I used the traditional summer slowdown to move to a new host and connect with an experienced team of professionals specialized in helping businesses develop converged Web and Mobile solutions in preparation for a new-look MSearchGroove.
But the real news is Pump Up The Volume: An Assessment of Voice-Enabled Web Search on the iPhone, MSearchGroove’s new-release white paper assessing the performance of voice search on an iPhone offered by ChaCha, Google and Vlingo (using Yahoo!), which you can download here. The report is especially timely, coming on the heels of today’s announcement by Google that it has fine-tuned the mobile app versions of its Google Voice service for Blackberry and Android. (More on the user experience via this detailed post at GigaOm.)
The top-level findings: ChaCha, a fast-growing SMS mobile search service available in the U.S. in the industry, “proved superior” to two other voice-enabled search options for the iPhone: the Google Mobile App with Voice and Vlingo for iPhone, a voice enabled application that allows users to direct their spoken queries to Google or Yahoo! (For the purposes of this study Vlingo provided a spoken interface to the Yahoo! search engine.)
ChaCha proved to offer exceptional results, with its human guides interpreting the search query accurately in the majority of cases. According to the study, ChaCha interpreted natural language search queries, that is, queries asked as questions, accurately in 94.4 percent of the tests and delivered an accurate search result in 88.9 percent of cases. The Google voice recognition technology interpreted queries accurately in 16.7 percent of tests and delivered accurate search results in 22.2 percent of tests. The Vlingo for iPhone voice recognition technology correctly interpreted queries in 72.2 percent of cases and delivered accurate results (via Yahoo!) in 27.8 percent of tests.
