Typical Scenario Demos

The A8550MA1 can perform on-device voice capture, speech recognition, semantic understanding, knowledge retrieval, translation, speech synthesis, and business control. AidVoice, the intelligent voice platform, combines these capabilities into pipelines, making it easy for developers to validate the full chain and further integrate it with their own devices and business systems.

AidVoice Intelligent Voice Demo

Demo Capability Overview

Scenario	Input	Processing Pipeline	Output
Command Control	Natural voice commands such as "go forward", "turn", "lights"	Voice capture → ASR → Intent recognition / Command formatting → Control interface	Structured commands, device execution results, voice feedback
Real-time Translation	Continuous Chinese speech or short sentences	Voice capture → Streaming ASR → Translation model → Subtitles / TTS	English translation stream, subtitles, optional voice playback
RAG Knowledge Q&A	Voice questions about local documents	ASR → Question rewriting → Top-K retrieval → LLM answer → TTS	Knowledge base-based answers, cited excerpts, optional voice playback
Meeting Transcription & Summarization	Continuous meeting speech	Streaming ASR → Text caching / Segmentation → LLM summarization	Real-time transcription, segment summaries, final minutes & action items

Real-time Translation Demo

The real-time translation demo demonstrates the complete process of Chinese speech input, streaming recognition, English translation, subtitle display, and voice playback.

1. Microphone captures Chinese speech.
2. ASR outputs recognized text.
3. The translation model generates English translations in streaming fashion.
4. The application continuously refreshes subtitles.
5. Optionally, TTS reads the translation aloud based on the scenario.

Demo Phase Metrics

Phase	Reference Result
ASR output → First translation token	~0.18 s
ASR output → Complete translation	~1.14 s
Translation complete → TTS write	~0.19 s

Other Demo Reference Metrics

Demo	Key Phase	Reference Result (This Demo)
Command Control	ASR output → Command output	< 1.5 s
RAG Knowledge Q&A	Wake → ASR output	~3.30 s
RAG Knowledge Q&A	ASR output → RAG retrieval complete	~1.99 s
RAG Knowledge Q&A	ASR output → First answer character	~5.27 s
Meeting Transcription & Summarization	Text cache trigger threshold	110 characters
Meeting Transcription & Summarization	Trigger → Model first packet	~0.21 s
Meeting Transcription & Summarization	Trigger → First summary character	~0.68 s

Test Notes

The above data comes from phase recordings under the current demo configuration and is intended to illustrate the pipeline and establish acceptance criteria. Actual results are influenced by model version, input length, audio environment, system load, knowledge base size, and output length. Please refer to the target version and actual test environment.

Project Integration Approach

1. Determine the scenario: Select a profile such as voice control, real-time translation, knowledge Q&A, or meeting summarization.
2. Select components: Enable ASR, TTS, LLM, RAG, translation, and device control interfaces as needed.
3. Configure business rules: Set trigger conditions, prompts, knowledge bases, output formats, and exception handling policies.
4. Integrate with customer systems: Connect to device APIs, databases, ticketing systems, or industry business platforms.
5. Test and accept: Verify accuracy, phase latency, end-to-end latency, resource usage, stability, and execution success rates.

Tip

The AidVoice Demo can serve as a starting point for functional validation. Developers can keep the standard pipeline while replacing models, prompts, knowledge bases, and business plugins to create intelligent voice applications tailored to specific products.
