【Problems with traditional English speaking tests】

Although the cultivation of communicative competence in English has been emphasized in English education in Japan, it has long been pointed out that teaching methods, assessment methods, and teaching materials have been inadequate. According to the Common European Framework of Reference (CEFR), a global language proficiency standard, English proficiency in the four language skills (reading, writing, listening, and speaking), especially speaking proficiency, is defined by factors such as expression richness, grammatical correctness, fluency, pronunciation, interactivity, and coherence. Among these factors, the existing automated English language proficiency tests have been pointed out to be insufficient in terms of “interactivity” and “coherence”, which are considered important for conversing with others. In principle, it is difficult to capture such interactive features in conventional reading-based tests, and it has been pointed out that such tests do not adequately reflect actual communicative competence.

【About LANGX Speaking】

In contrast to the problems with conventional English tests, LANGX Speaking uses a conversational AI agent to elicit the learner’s abilities through natural interviews and role-playing dialogues, and then makes a comprehensive assessment of speaking ability. The more you talk, the more you learn. The more you converse with the agent, the more it learns about you and the more relevant feedback it can deliver (patent pending).

  1. Natural Conversation to Elicit English Conversation Skills: At the beginning of the LANGX Speaking test, the AI agent creates a relaxed atmosphere by talking to the test taker in a way that eases their tension. During the interview that follows, the agent playing the role of the interviewer will be there during the conversation with the test taker, offering some pleasantries and waiting while the test taker thinks of a response. If the candidate is at a loss for an answer and the conversation becomes stilted, the interviewer will lead the conversation to another topic, thus providing an experience similar to a real interview. The system assesses the English level of the respondent’s speech and automatically adjusts the difficulty level of the questions. In the latter half of the interview, a simple discussion dialogue is also developed.
  2. Assesses true English speaking ability: Using speech data collected through interactive conversations with agents, LANGX Speaking automatically assesses a candidate’s speaking ability based on six aspects (CEFR criteria): expression richness, grammatical correctness, fluency, pronunciation, interactivity, and coherence. By taking LANGX Speaking, test takers are able to check their own level of English speaking ability and understand their own strengths and weaknesses in English speaking, which can then be used to improve their English language learning. The latest assessment model significantly exceeds the accuracy of CEFR assessment experts.
  3. Low price: Compared to in-person speaking proficiency tests conducted by human experts (which typically cost between 5,000 yen and 20,000 yen), LANGX Speaking is available for less than 2,000 yen per test through the use of AI.

Once each educational and general institution signs the LANGX Basic contract and order the required number of LANGX Speaking test tickets, test takers affiliated with that institution are able to the speaking test. Each test taker accesses the LANGX Speaking website via a web browser on their laptop, registers for the test tickets distributed by their institution, and then takes the speaking test as easily as if they were in an online meeting (no special equipment or software required). The results are returned to the learner within a few minutes in a normal situation.

The admin user of each institution can check the test status and improvement of the abilities of all the test takers in the institution from the dedicated LANGX Speaking customer console. The testing system, which is constantly evolving, will enable more detailed and accurate diagnostic results and growth processes to be viewed and utilized for curriculum planning and other purposes based on data analysis.

▼LANGX Speaking Adoption by Waseda University

Waseda University has officially adopted LANGX Speaking as their English proficiency assessment test for their English conversation class “Tutorial English” from the 2023 academic year. The test is expected to be used by more than 10,000 students annually. As of March 2023, approximately 4,000 new students took the test and the test results was used for class placement in the English conversation class.

Tutorial English is a small-group class with a maximum of four students per group, focusing on the development of English speaking skills. The course is one of the signature courses at Waseda University. LANGX Speaking was officially adopted in the 2023 academic year for the purpose of measuring learning effectiveness and class placement before and after the course. By adopting a technology that deeply measures interpersonal communication skills in English, it is expected that students will be able to take classes at more appropriate levels and further improve their learning effectiveness.

Equmenopolis landed on SXSW EDU Launch and EXPO to showcase the latest LANGX product

Equmenopolis pitched the latest LANGX to global educators and investors at SXSW EDU Launch, and exhibited a demo at EXPO in Austin, Texas.

Yoichi Matsuyama, CEO of Equmenopolis, pitched at SXSW EDU Launch

We introduce the LANGX – An Immersive Language Experience platform, where you are immersed in real-world simulations to demonstrate your language abilities through dynamic conversations with AI characters with different backgrounds and personalities.

When you enter the LANGX universe, your first step is to be interviewed by an AI character. It can adaptively change topics ranging from simple daily-life topics to complex social issues. While talking, AI dynamically assesses your ability, and gives you personalized responses. In case you don’t understand what the AI asked, it will rephrase or clarify the questions. After the interview, you will get your final score and suggestions on what to learn next.

We are very proud that our assessment model is more accurate than a group of human experts, which takes all the possible conversational features into account in our deep model.

We exhibited the new version of LANGX at SXSW EDU EXPO, and got attentions from educators and investors. Thank you for coming to our booth!
