a language by passively turning pages in a textbook.
You actually progress when the language talks again to you.
While you see pictures, hear actual sentences, attempt to communicate, and get suggestions, every thing lastly clicks in your head.
Prior to now, you wanted a trainer by your facet always to get that sort of suggestions.
At present, generative AI can play that function in your telephone or laptop, like an AI language tutor you should utilize any time.
After I began studying Mandarin ten years in the past, I noticed many foreigners struggling to be understood by locals in on a regular basis conversations due to poor pronunciation.
It satisfied me that with out good pronunciation, a wealthy vocabulary is ineffective.
I nonetheless bear in mind sitting in my residence in Shanghai, repeating the identical sentence many times, with out anybody to appropriate me.
Years later, after I found generative AI, I remembered the engineer in China who was fighting grammar books and tones.
I needed to construct instruments that might have helped me previously.
As a startup founder, I do not need a lot free time, so I wanted a option to construct and take a look at new instruments shortly.
That’s the reason I turned to n8n to construct assistants that might have made my Chinese language observe a lot simpler.
On this article, I’ll present how I exploit n8n and multimodal AI to construct a “examine companions” for language studying that:
- Right my pronunciation utilizing Textual content-to-speech capabilities
- Create workout routines to review vocabulary lists
- Generate pictures as an instance phrases or contexts for flash-card model observe
Collectively, they present how AI and low-code platforms like n8n can help anybody studying a posh language.
Even with every day utilization, all of those collectively value lower than 1 euro per 30 days.
AI For Pronunciation And Oral Comprehension
My identify is Samir, a provide chain skilled who struggled with Mandarin throughout his six-year keep in China.
Let me introduce you to Yin, the AI-powered Language coach I developed final week.
This can be a net utility I designed to help my Chinese language studying journey after greater than 5 years with out practising.
It consists of three options:
- Pronunciation Workouts
- A number of Selection Questions (MCQ)
- Flash Playing cards
I’ll use every characteristic to reveal how I exploit multimodal AI to enhance my studying comprehension, listening, and pronunciation in Mandarin.
Why is pronunciation in Mandarin so Vital?
Let me share an actual story from China to spotlight the significance of utilizing the proper tone in Mandarin.
At some point, I used to be invited to a job interview on the largest Chinese language categorical firm, valued at billions.
All the dialog was in Chinese language.
I had fastidiously ready my sentences, highlighting how I used knowledge science to enhance warehouse operations.
At one level, I needed to say: “I exploit knowledge science to enhance choosing productiveness within the warehouse.”
The verb “choosing” means taking items from cabinets or racks in a warehouse.
In Chinese language, my colleagues used the verb 拣货 (jiǎn huò) to explain this course of.
However as a substitute of claiming jiǎn huò, I mentioned jiàn huò.
Which is a very totally different phrase that you just positively don’t wish to use in a job interview.
To maintain it well mannered right here, let’s say jiàn huò is a impolite phrase.
The supervisor burst out laughing.
I didn’t perceive why till I debriefed with the headhunter later and repeated the sentence for her.
That second taught me that pronunciation in Chinese language isn’t nearly sounding pure.
You’ll be able to know 1000’s of phrases, but when your tone is improper, folks received’t perceive you.
Because of this the primary characteristic of my app is an AI pronunciation coach.
Utilizing Speech-to-Textual content Recognition to Practise
Utilizing speech-to-text and reasoning, the app listens to what I say, compares it with the goal sentence, and offers suggestions on which tones or syllables have been off.
The main target right here is on enhancing my pronunciation of logistics and provide chain phrases (my discipline of experience).
For every phrase, we now have:
- The phrase in Simplified Mandarin Characters: 合同
- The sentence used to practise my pronunciation: 我们需要在发货前签署这份运输合同。
- The English translation: We have to signal this transport contract earlier than delivery the products.
For newcomers, we are able to even add phonetics (Mandarin pinyin) utilizing the toggle.
Methods to observe pronunciation?
I simply need to press the mic button on the backside to file my sentence.
The recording is routinely despatched to the backend for evaluation that compares my pronunciation with the proper one.
A number of seconds later, I obtained my suggestions.
The suggestions is sort of detailed; it focuses on the phrases that you just mispronounced.
It’s practically like having a private trainer correcting me in actual time, besides this one by no means will get drained.
After all, this received’t exchange an awesome trainer in a one-on-one lesson, however it will probably assist you to practise after courses.
After I began studying Mandarin, I used to spend evenings (after work) alone, repeating easy sentences to familiarise myself with the nuances of tones.
I didn’t have a suggestions loop on the time; this software would have been very useful.
How does it work?
Textual content-to-speech and reasoning capabilities of GenAI
The backend is an easy n8n workflow linked to the frontend through a webhook.
The text-to-speech capabilities are used to transcribe the audio file despatched by the entrance finish into phonetics (pinyin).
The output of this Gemini audio transcription node consists of the phonetics:
[
{
"content": {
"parts": [
{
"text": "zuò pǐn huò zǒnggòng fàng zài èrshí ge tuōpán shàng.n"
}
],
"function": "mannequin"
},
"finishReason": "STOP",
"avgLogprobs": -0.16858814502584524
}
]This pinyin is then despatched to the AI node Pronounciation Evaluation together with the goal pronunciation.
On this instance, I mispronounced the penultimate phrase.
That is exactly what the agent talked about in his suggestions.
This exhibits how we are able to use text-to-speech capabilities, mixed with the reasoning of generative AI fashions, to enhance our pronunciation.
This may be tailored to any language.
What about picture era and speetch-to-text?
Generative AI for Content material Technology
When you observe the person interface of the applying, you discover that every phrase has:
- An illustrative Picture
- A sentence for the context
- Audio transcription accessible through the microphone icons
This content material is generated utilizing AI fashions to supply a wide range of educating supplies for the second characteristic: flashcards.
Textual content-to-Speech Options
An effective way to practise pronunciation is to pay attention and repeat.
Due to this fact, earlier than recording my sentence, I can learn to pronounce the phrase utilizing this primary speech-to-text characteristic.
For this, I exploit Google’s Textual content-to-Speech API as it’s fairly handy and free.
from gtts import gTTS
def generate_speech(textual content: str, lang: str):
filename = f"{uuid4().hex}.mp3"
filepath = f"./knowledge/gtts/{filename}"
tts = gTTS(textual content=textual content, lang=lang)
tts.save(filepath)With a few traces of code, you possibly can generate the text-to-speech of any phrase utilizing the right language code.
That is precisely what I used within the software to generate flashcards that I introduced on In the direction of Knowledge Science three years in the past.
The concept on the time was to enhance my listening comprehension by including audio to the flashcard solutions.
What about lengthy sentences?
The issue with Google Textual content-to-speech is the robotic voice.
Luckily, we now have eleven labs.
The workflow above is linked to the app through webhook.
The Eleven labs node that takes the output of the AI Agent Generate Instance to generate the audio model of the sentence.
The person can now hearken to the sentence pronounced “like” a local speaker.
What’s remaining? Questions and illustrations …
Educating materials era
As defined within the earlier part, the sentences are additionally generated utilizing AI.
The AI Agent node, powered by Gemini, takes the phrase to review as enter and makes use of the system immediate under to generate a sentence.
You're a Chinese language language tutor for professionals.
Given a Chinese language phrase, you MUST return a JSON object with EXACTLY these keys:
- "sentence": a brief Chinese language sentence utilizing the phrase in a enterprise or
daily-life context
- "pinyin": the pinyin of the complete sentence
- "english": the English translation of the sentence
Return ONLY legitimate JSON. No explanations, no backticks, no additional textual content.
Instance:
{
"sentence": "我去仓库检查货物。",
"pinyin": "Wǒ qù cāngkù jiǎnchá huòwù.",
"english": "I'm going to the warehouse to examine the products."
}That ensures a virtually infinite number of workout routines.
And the cherry on the cake is the picture generated with Gemini’s Nano Banana to assist us join a phrase to its context.
After studying 1000’s of Chinese language characters, I observed that pictures assist with memorising new phrases.
That is exactly what I exploit within the flashcards characteristic.
The n8n backend offers to the front-end:
- The phrase in Chinese language that you just wish to be taught with pinyin and English translation
- An instance sentence and its translation generated by GPT
- An illustrative picture generated by Gemini
The entrance finish then manages the card-flipping mechanism.
If you wish to recreate this resolution tailor-made in your wants, I’ve shared an identical workflow on my GitHub.
Do you want multiple-choices questions? Gen AI may help!
Generate Workouts from a vocabulary record
For the final characteristic, we generate multiple-choice inquiries to be taught the identical vocabulary record.
We ask Gemini to generate questions from the vocabulary record, utilizing multiple-choice choices with just one appropriate reply.
[
{
"output": {
"question": "Which of the following is the correct Chinese translation for 'Variable Pricing'? Please answer with A, B, C, or D.",
"options": {
"A": "仓库",
"B": "可变定价",
"C": "卡车司机",
"D": "投标"
},
"correct": "B",
"right_feedback": "Great job! 可变定价 (kě biàn dìng jià) means Variable Pricing.",
"wrong_feedback": "Oops! The correct answer is B: 可变定价 (kě biàn dìng jià), which means Variable Pricing."
}
}
]The front-end makes use of this output to supply the questions with tailored suggestions.
The backend of this characteristic relies on an n8n workflow that I additionally shared on my GitHub: AI-Powered Language Instructor utilizing GPT.
Conclusion
I developed this app to experiment with how AI might improve my studying capabilities.
After practically 5 years with out talking Chinese language, this multimodal AI assistant has confirmed to be an awesome assist.
All the backend is constructed on n8n for speedy prototyping and seamless integration.
You aren’t acquainted with n8n and wish to be taught?
I’ve a whole tutorial, designed for newcomers, on my YouTube channel that may information you from occasion creation to credential setup.
After this tutorial, it is possible for you to to make use of any of the workflows shared in my repository.
As I do not need time to decide to in-person Chinese language courses, I can have an assistant who will adapt to my schedule.
Can we do higher?
On the “roadmap” of this small facet mission, I’ve:
- Including complicated grammar workout routines that might be executed orally (combining studying comprehension, grammar and pronunciation)
- Implementing a writing module that might appropriate my calligraphy utilizing picture processing
Relying on my availability, I’ll intention to ship it by Q1 2026.
