# Qwen2-Audio
Qwen2-Audio is a SOTA small-scale multimodal model that handles audio and text inputs, allowing you to have voice interactions without ASR modules. Qwen2-Audio supports English, Chinese, and major European languages,and also provides robust audio analysis for local use cases like:
- Speaker identification and response
- Speech translation and transcription
- Mixed audio and noise detection
- Music and sound analysis
## We're bringing Qwen2-Audio to edge devices with Nexa SDK, offering various quantization options.
- Voice Chat: Users can freely engage in voice interactions with Qwen2-Audio without text input.
- Audio Analysis: Users can provide both audio and text instructions for analysis during the interaction.
### Demo
## How to Run Locally On-Device
In the following, we demonstrate how to run Qwen2-Audio locally on your device.
**Step 1: Install Nexa-SDK (local on-device inference framework)**
[Install Nexa-SDK](https://github.com/NexaAI/nexa-sdk?tab=readme-ov-file#install-option-1-executable-installer)
> Nexa-SDK is a open-sourced, local on-device inference framework, supporting text generation, image generation, vision-language models (VLM), audio-language models, speech-to-text (ASR), and text-to-speech (TTS) capabilities. Installable via Python Package or Executable Installer.
**Step 2: Then run the following code in your terminal to run with local streamlit UI**
```bash
nexa run qwen2audio -st
```
**or to use in terminal**:
```bash
nexa run qwen2audio
```
### Usage Instructions
For terminal:
1. Drag and drop your audio file into the terminal (or enter file path on Linux)
2. Add text prompt to guide analysis or leave empty for direct voice input
### System Requirements
💻 **RAM Requirements**:
- Default q4_K_M version requires 4.2GB of RAM
- Check the RAM requirements table for different quantization versions
🎵 **Audio Format**:
- Optimal: 16kHz `.wav` format
- Other formats and sample rates are supported with automatic conversion
## Use Cases
### Voice Chat
- Answer daily questions
- Offer suggestions
