Channel Corporation launches Voice ALF AI phone agent

Channel Corporation officially launched Voice ALF, a generative AI phone call agent that handles customer consultations by voice, according to datanet.co.kr. The company announced the launch on October 21, 2026, alongside a feature called ALF Marketing that lets the AI call customers first under specified conditions.

Voice ALF extends ALF, the company's existing chat consultation AI agent, to phone calls and covers inbound inquiry handling. Under ALF Marketing, the AI places outbound calls to customers based on conditions set by the business.

The agent runs on Channel Corporation's in-house Turn Detection model, which analyzes intonation and hesitation to judge whether a customer has finished speaking. In an analysis of about 10,000 AI phone order records from Channel Talk's in-house cafe, the company found that in 87% of cases where Voice ALF waited because it judged speech had not ended, the customer's request continued within 1.5 seconds.

Korean-language speech model built in-house

Channel Corporation also developed its own Korean consultation-specialized text-to-speech system, trained on voice data from real Channel Talk counselors. The company says it handles mixed Korean-English expressions, dates, times and URLs.

Example uses include B2B sales, where Voice ALF automatically calls leads who submit consultation requests on a website, and A/S centers, where the AI checks product operation and sends follow-up guidance by text message.
