Lesson 1 - Exhibit Navigation: Voice Guide Station
Challenge 1-1, 1-2, 1-3
Suggested time: 45–50 minutes. For younger students or first-time users, this lesson may be extended to 60 minutes.
Students will explore how AI can help visitors in a museum find exhibits, understand information, and interact with a simple voice guide station.
I can describe how AI can support visitors at a museum guide station.
I can explain how a voice command can represent a visitor's request.
I can explain that the voice guide uses speech recognition technology.
Engage
2 min.
Museums are public spaces where visitors explore exhibits, ask questions, and learn new stories.
Different visitors may want to explore different areas. How can a voice guide station help them quickly find what they are looking for? Let’s try it.
Background
3 min.
How does the guide station understand a visitor's voice?
The K10 has built-in microphones. It listens for a wake word first. After it wakes up, the speech recognition function can match short spoken commands, such as “exhibits” or “portraits.”
How do we use the Voice Guide Station? How does it understand our commands? Let us try it and read the program together.
Required items:
| Item | Use in this lesson |
|---|---|
| UNIHIKER K10 | Runs the voice recognition program and shows guide pages. |
| USB cable | Connects the K10 to the computer. |
| Computer with Mind+ | Uploads the starter program and modified program. |
| Starter program | Provides two sample commands: exhibits and portraits. |
| Building instruction and building blocks | Used to build the museum voice guide station. |
Build and Connect
5 min.
| Build together by the Building instruction. |
• After groups finish building, have them prepare to connect the K10 and upload the starter program.
Explore Function
10 min.
Open Coding page - Mind+, connect the K10, and upload the starter program.
Challenge 1-1: Try the Voice Guide
| Before testing, remind students to speak clearly and stay close to the K10. Ask: What does the screen show after the wake word is recognized? What does the screen show after each command? Does the response match the spoken command? |
| Guide students to read the command blocks: - command ID 0 -> "exhibits" - command ID 1 -> "portraits" |
After groups finish reading the program, prompt them to discuss the questions below:
• How does the Voice Guide Station work? What are its input, process, and output?
• What does the Voice Guide Station recognize as its main input?
• Where have you seen a similar voice-controlled device in daily life?
Explore AI technology
15 min.
Challenge 1-2: Think Like the AI Guide
| Ask students to find three parts in the code: voice command word, command ID, and guide page. Then complete the process and decision flowchart. Guide students to understand that the command ID is the bridge between speech recognition and the program’s decision. The K10 recognizes a spoken command, returns a command ID, and then the program uses that ID to show the correct guide page. |
| Introduce speech recognition as the key AI technology used in the Voice Guide Station. Connect it to familiar voice-controlled devices students may have used before. |
Introduce the key technology.
A voice command is a short phrase that represents what the visitor wants.
• Voice input: The visitor says a command.
• Process: The AI voice model matches the sound to a command ID,.
• Output: The program shows the guide page that matches the command.
• Definition
Speech Recognition – a technology that helps a computer recognize spoken words. In this lesson, the K10 listens to a voice command and matches it with a command ID.
AI Model – a system that has learned patterns from data. A speech recognition model helps the device match a new spoken word with a known command.
Discuss.
Guide students to discuss speech recognition technology. Ask students to look for short videos, product pages, or beginner-friendly technology articles.
Before discussing, ask students to share:
• Where have you heard a machine understand people’s speech?
• What can people do with voice commands?
• How is that example different from our AI Voice Guide Station?
Program Challenge
10 min.
Prompt students to think about other museum areas that may need navigation,or other natural voice interactions a visitor might use.Then have them add new commands to improve the Voice Guide Station.
Questions:
- What new command word will visitors say?
- What command ID will you use?
- What page should appear?
Challenge 1-3: Add a New Guide Command
| Have students plan their design on the Challenge Card before editing the program. |
| Remind students to program, upload the program, and test the new command. |
Summary—Key AI ideas review
5 min.
In this project :
• The voice command represents a guide request.
• The speech recognition can recognizes the spoken command.
• The program uses the command ID to show the correct guide page.
• AI can help visitors, but people still design the commands and guide information.
AI Program Block Review
| Blocks | Description |
|---|---|
| Sets the speech recognition mode, wake listening time, and recognition language. The wake time is measured in milliseconds (ms). |
| Adds a voice command and assigns it a command ID. Command IDs range from 0 to 199. Use short, clear command words, preferably 2–5 syllables. |
| Checks whether a command with the specified ID has been recognized after the wake word. |
| Checks the current speech recognition status. |
