About this app

Is that English relevant to you?

SpeakIn6 is an AI language learning app that transforms what you want to know and talk about into English content tailored to your level.

Events from today, news that caught your attention, things you usually ask the AI, things you want to talk to someone about.

Your own interests and experiences become listening and speaking materials.

【Understand. Speak. Communicate.】

With SpeakIn6, you'll increase the expressions you can use in your own words by repeatedly "listening → memorizing → speaking" English that's relevant to you.

■ Listen to what you want to know in English at your level

The AI ​​creates listening content tailored to your level based on themes you're interested in.

After checking the meaning, instead of immediately translating into Japanese, focus on the English sounds, rhythm, and accent and listen repeatedly.

■ Listen to the example and imitate the rhythm and accent

You don't need to pronounce every single sound like a native speaker.

However, to be understood, it's crucial to carefully listen to and imitate the rhythm and accent of the example.

In SpeakIn6, you repeatedly listen to the example audio and imitate its rhythm and accent.

Even if there are slight differences in pronunciation, by getting closer to the example rhythm and accent, it becomes easier for the AI ​​to recognize, leading to more effective English communication.

■ Translate what you want to say into English and speak it aloud

You can practice translating things that happened today or things you want to tell someone into English.

Instead of just memorizing English words, you'll learn phrases that can be used directly in real English conversations by listening to examples and imitating them.

■ Conversation with an AI character

Practice the English you've learned immediately by conversing with an AI character.

You can practice speaking through chats with AI characters that share your interests or through role-playing scenarios simulating real-life situations.

Communicate.

Listen to the other person's response.

If you don't understand, ask for clarification.

Try saying it again.

Through this repetition, you'll turn the English you've learned into "communicative language." ■ Reduce "I Can't Say It" by Using Translation

Even if you can't think of the expression you want to say during an English conversation, you can check it with translation.

You don't need to think only in English from the beginning.

First, prepare what you want to say, say it aloud, and use it in actual conversation.

■ Review with My Dictionary

Save new expressions used in conversation and phrases you want to use next in your own personal dictionary.

The goal is not just to look it up once and be done with it, but to review it repeatedly and aim to be able to say it on your own next time.

【Learning Design Based on Second Language Acquisition Research】

SpeakIn6 designs its learning experience based on the concepts advocated in second language acquisition research: "exposure to a language you understand," "actually putting what you want to say into words," and "exchanging meaning in conversation."

Representative Research and Literature:

Stephen D. Krashen — Comprehensible Input / Input Hypothesis
The Input Hypothesis: Issues and Implications (1985)

Merrill Swain — Output Hypothesis
The Output Hypothesis: Just Speaking and Writing Aren't Enough (1993)

Michael H. Long — Interaction Hypothesis
The Role of the Linguistic Environment in Second Language Acquisition (1996)

SpeakIn6 incorporates these research findings, combining AI-powered level adjustment, personalized learning materials, listening and speaking practice, and AI-assisted conversation experiences.

*This does not indicate that these researchers supervise or endorse SpeakIn6. Furthermore, learning effectiveness is not guaranteed solely based on specific theories or literature.

【Recommended for those who:】

・Can understand spoken English, but struggle to speak it themselves

・Want to practice English listening and speaking together

・Aren't interested in the themes of typical English learning materials

・Want to acquire a natural English rhythm and accent

・Want to talk about their daily life and interests in English

・Don't know what to talk about in AI English conversation

・Want to learn English at their own level

Instead of adapting yourself to the learning materials,

adapt the learning materials to yourself.


Ask what you want to know.

Imitate the rhythm and accent of the example.

Memorize what you want to say.

And then, actually speak it.

With SpeakIn6, make English about yourself your own.

Supported languages: English, Japanese, French, Spanish
