DL E&C said D-VOICE summarized customer consultations within 1 minute

WorkingCompany's own claimOfficial ↗

Problem

Employees manually reviewed consultation records and selected keywords to classify customer requests. This made preparing information for subsequent consultations labor-intensive.

Approach

DL E&C worked with Microsoft to add GPT-4 technology to its DLake data platform. D-VOICE transcribed calls and removed personal information before sending the content for summarization. It then classified summaries by keyword and stored them for staff handling later consultations. The company applied the system to sales and after-sales customer service.

Results

≤1 minuteconsultation summarization time reported by DL E&CCompany's own claim[1]

Takeaway

The workflow produced classified consultation records for subsequent staff use. The disclosed summary time did not establish an improvement in customer satisfaction.
