Japan telecoms giant creates AI filter that calms angry customer voices in call centres
- Survey shows nearly half of staff harassed, get abusive language, threats, SoftBank works with Tokyo University, starts using technology next year

We all know the frustration of not getting our queries dealt with by customer services, or being kept waiting too long.
Some people take it out on the person dealing with the issue. Imagine being that person.
Now Japanese telecoms giant SoftBank has created an artificial intelligence (AI) filter that masks angry customers’ voices with a softer tone, to ease pressure on staff.
In Japan, customer harassment, or kasu-hara, has increasingly become a problem in the workplace alongside power harassment and sexual harassment.
According to a 2024 survey conducted by Japan’s biggest union, UA Zensen, of about 30,000 staff working in service and other sectors, 46.8 per cent said they had experienced customer anger or intimidation in the past two years.

Incidents included abusive language, repetitive complaints, threats and unreasonable demand for apologies.
