Amazon has applied for a patent for an audio system that detects the accent of a speaker and changes it to the accent of the listener, perhaps helping eliminate communication barriers in many situations and industries. The patent doesn’t mean the company has made it (or necessarily that it will be granted), but there’s also no technical reason why it can’t do so. The application, spotted by Patent Yogi , describes “techniques for accent translation.” Although couched in the requisite patent-ese, the method is quite clear. After a little translation of my own, here’s what it says: In a two-party conversation, received audio is analyzed to see if it matches with one of a variety of stored accents. If so, the input audio from each party is outputted based on the accent of the other party. It’s kind of a no-brainer, especially considering all the work that’s being done right now in natural language processing. Accents can be difficult to understand, especially if you haven’t spoken with an individual before, and especially without the critical cues from facial and body movements that make in-person communication so much more effective. The most obvious place for an accent translator to be deployed is in support, where millions of phone calls take place regularly between people in distant countries. It’s the support person’s goal to communicate clearly and avoid adding to the caller’s worries with language barriers. Accent management is a major part of these industries; support personnel are often required to pass language and accent tests in order to advance in the organization for which they work. A computational accent remover would not just improve their lot, but make them far more effective. Now a person with an Arabic accent can communicate just as well with just about anyone who speaks the same language — no worries if the person on the other end has heavily Austrian, Russian or Korean-accented English; if it’s English, it should work.
