Unlike Siri or the other integrated options, Hound doesn't split the audio speech recognition from the language processing part, which makes it incredibly fast in processing and replying to your spoken query. If you don't believe us, just watch the video demo below, where the beta gets compared to Siri, Google Now and Cortana.
That is not all there is to it, though - unlike the highly structured, overly robotic nature of questions you can ask Siri or Google Now, Hound deals with much more complex queries, resembling natural language. You can ask it, for example, to show you hotels in the city you are traveling to, then dish out requests like "but only single rooms with sea view," and add "for less than $200 a night," now that you thought of your budget.
SoundHound CEO mentioned they are not worried about the competition much, as the company's years in audio processing expertise built around song recognition will keep it abreast any startup that dares to challenge Hound's abilities. Judging from the comparison below, he has every right to be so confident.
