Alexa Is Still Taking Language Lessons
August 24, 2018
Though Amazon has been aware of the problem for a while, Alexa still responds better to people who sound like those she grew up with than she does to others. It is a problem many of us can relate to, but one the company really needs to solve as it continues to deploy its voice-activated digital assistant worldwide. TheNextWeb cites a recent Washington Post study as it reports, “Alexa Needs Better Training to Understand Non-American Accents.” It is worth noting it is not just foreign accents the software cannot recognize—the device has trouble with many regional dialects within the US, as well.
“The team had more than 100 people from nearly 20 US cities dictate thousands of voice commands to Alexa. From the exercise, it found that Amazon’s Alexa-based voice-activated speaker was 30 percent less likely to comprehend commands issued by people with non-American accents. The Washington Post also reported that people with Spanish as their first language were understood 6 percent less often than people who grew up around California or Washington and spoke English as a first language.Amazon officials also admitted to The Washington Post that grasping non-American accents poses a major challenge both in keeping current Amazon Echo users satisfied, and expanding sales of their devices worldwide. Rachael Tatman, a Kaggle data scientist with expertise in speech recognition, told The Washington Post that this was evidence of bias in the training provided to voice recognition systems.‘These systems are going to work best for white, highly educated, upper-middle-class Americans, probably from the West Coast, because that’s the group that’s had access to the technology from the very beginning,’ she said.”
Yes, the bias we find here is the natural result of working with what you have where you are, and perhaps Amazon can be forgiven for not foreseeing the problem from the beginning. Perhaps. The article grants that the company has been working toward a resolution, and references their efforts to prepare for the Indian market as an example. It seems to be slow going.
