Service Overview

Features & Benefits

Use Cases

COTOHA, a communication engine, provides customers with responses for inquires, problem solving and business processing such as placing orders and issuing invoices by communicating with users and by analyzing and understanding spoken and written language with a high-level of accuracy.

COTOHA understands natural spoken and written language, communicates accurately with users in place of a human operator and performs business processing such as accepting reservations, troubleshooting and various other procedures.

COTOHA incorporates the following features:

①Comprehension of English/Japanese context

COTOHA analyzes the meaning of user speech by labeling concepts or relationships such as subject, object and time of action. She communicates accurately by memorizing data for each individual user.

(1)Understanding and memorizing the context of English/Japanese language

②Flexible interaction

COTOHA prepares “slots” for elements required for answers, then acquires elements for unfilled slots automatically through conversation. She is capable of natural conversation including responding to unexpected questions from users and returning to the original subject.

③Reduced set-up workloads

Setting up "slots" reduces the workload when setting up branches that tend to increase in proportion to the number of elements. In addition, a technology for absorbing orthographic variants reduces the workload of inputting response scenarios which tend to be complicated.

(3)Reduction of set-up operations workloads

④Memorization and expanding response

When a user has a problem or complicated request that cannot be resolved by COTOHA, she escalates the conversation to a human operator. COTOHA cumulatively memorizes human interactions and uses this information in conversation to flexibly expand her response capabilities.

(4)Memorizing and expanding response flow
