1. Product Introduction
TocoTalk is an AI-powered bilingual picture book reader designed for children aged 1–10.
Using physical picture books as the medium and integrating AI large-model technology, it creates
an immersive language enlightenment environment. With a simple “tap and point”, children can
make picture books “speak”, developing language competence, expression ability and reading
interest through multi-sensory interaction.

2. Detailed Core Functional Modules
2.1 Audio Module
System prompt tones have the highest priority; media sound mutes during prompt playback.
The speaker and power amplifier shut down when no audio is pending.
Core Functions:
• System Voice Prompts: Auditory feedback for power on/off, network connection
success/failure, recognition start/end and other statuses.
• Text-to-Speech (TTS): Core reading function that converts recognized text into
speech via AI voice synthesis.
• Voice Tone Settings: Multiple tones switchable to suit children’s preferences,
configurable via App/mini-program (only one tone supported for now).
• Language Settings: Supports reading in multiple languages such as Chinese,
English and Cantonese, configurable via App/mini-program.
• Volume Control: Multi-level system volume adjustment via device buttons or
remote App/mini-program settings.
• Technical Association: Interacts closely with cloud AI speech synthesis services or
local TTS engines, receiving text instructions from the AI processing module.
Playback :
• Exclusive Playback: Clears previous content and plays the specified audio.
• Interruption Rule: Photo-based playback cannot be interrupted and takes priority
over all other audio.
2.2 Display Module
Core Functions
• Status Indication: Clearly displays device status via a small screen (or LED icons).
• Main Display Elements:
o Wi-Fi connection status
o Cloud connection status
o Battery status (level and charging)
o Scanning mode status
o Firmware upgrade status
2.3 Image Capture & AI Recognition Module
Core Functions
• Image Capture: Built-in camera for fast, clear shooting of book pages and scanning
Wi-Fi QR codes for system configuration.
• Optical Character Recognition (OCR): Preprocesses captured images
(correction, noise reduction) and accurately recognizes text via AI models.
• Natural Language Processing (NLP): Performs semantic analysis on
recognized text to ensure natural phrasing, intonation and emotion during reading.
• Core Technology:This module is the technical foundation of the product, relying on
high-precision OCR algorithms and powerful NLP models processed in the cloud.
2.4 Button Module
1. Photo Button (2-stage)
o Half-press: Activates alignment light for framing.
o Full-press: Triggers photo recognition; keep steady until the “drop” sound.
2. Translate Button
o Short press: Translates the last recognized content.
o Long press: Enters Wi-Fi QR code pairing mode; short press to exit.
3. Repeat Button
o Short press: Repeats the last recognized content.
o Long press: Toggles between “Reading Mode” and “Picture Description Mode”.
4. Volume – / 5. Volume +: Adjusts volume.
5. Power Button
o Long press 2s: Powers on.
o Long press 5s: Powers off.
o Double-click: Toggles “Background Listening Mode”.
6. Point-Read Button: Press down for point reading.
7. Reset Button: Forces device restart.
2.5 Indicator Light Module
• Range Indicator Light: Marks effective shooting range; approximately 1.2cm blind
spot at the front base.
• Charging Indicator Light: Near charging port; red solid = charging, green solid = fully
charged.
2.6 Shake Module
Shake the device to trigger random short stories, ancient poems, etc. Content type
configurable via App/mini-program.
2.7 Background Listening Module
Enable/disable by double-clicking the power button; plays preset content continuously.
Playlist created in App/mini-program.

Interaction Logic
The App communicates with the reader via cloud services for real-time synchronization of
commands and status data.
2.9 Membership System Module
Basic Membership / Advanced Membership
Note: This product relies on cloud AI computing power and requires membership service
support.
2.10 Firmware Upgrade (OTA)
• Automatically checks for updates on boot; downloads new versions silently in the
background.
• Applies upgrade on next restart (ensure sufficient battery). Do not power off during
upgrade.
• Displays upgrade icon and voice prompt when updates are available. Automatically
restarts and prompts upon completion.
3. System Workflow
The device operates in a closed-loop system in the following sequence:
1. Trigger: Aim reader at book page and press photo button.
2. Image Capture: Camera activates and captures high-resolution image.
3. Image Transmission: Image data sent to AI processing unit (uploaded to cloud server via
Wi-Fi).
4. AI Recognition & Processing
o OCR Recognition: AI model identifies text areas and converts to
machine-readable text.
o NLP Processing: Proofreads, segments and analyzes semantics to generate
structured text with prosody.
5. Speech Synthesis (TTS): Processed text sent to TTS engine, synthesizing audio in selected
language/tone.
6. Audio Playback: Audio stream sent to speaker for playback, completing the “shoot–
recognize–read” process.
4. Key Technologies & Dependencies
• High-precision OCR technology: Ensures high recognition rate for various fonts and
layouts.
• High-quality TTS technology: Delivers natural, expressive voice close to human speech.
• Stable network connection: Cloud-based AI processing requires reliable Wi-Fi.
