案例部署
步骤一：安装 AidVoice SDK
bash
# 安装AidLite QNN 2.36版本
sudo aid-pkg update
sudo aid-pkg install aidlite-sdk
sudo aid-pkg install aidlite-qnn236
# 安装 AidVoice SDK
sudo aid-pkg -i aidvoice-sdk步骤二：模型获取
bash
# 获取 MeloTTS-English
mms get -m MeloTTS-English -p fp16 -c qcs8550 -b qnn2.31 -d /home/aidlux/melotts-english
cd /home/aidlux/melotts-english
unzip melotts_en_woman_qcs8550_qnn231_fp16_aidlite.zip步骤三：测试代码编译
bash
# 拷贝测试代码
cp -r /usr/local/share/aidvoice/examples /home/aidlux/aidvoice
# 编译
cd /home/aidlux/aidvoice/tts/cpp/
mkdir -p build && cd build
cmake ..
make步骤四：麦克风 ID 确认
接入 USB 麦克风
bash
cd /home/aidlux/aidvoice/tts/cpp/
sudo ./test_tts -c可以看到如下输出，Jabra SPEAK 410 USB 的 ID 为 15
bash

- Capture device #13: 'kalama-qrd-snd-card, (14)'
- Capture device #14: 'kalama-qrd-snd-card, (15)'
- Capture device #15: 'Jabra SPEAK 410 USB, USB Audio'步骤五：运行例子
bash
cd /home/aidlux/aidvoice/tts/cpp/build
# -m 模型路径
# -i 麦克风 ID
sudo ./test_tts -m /home/aidlux/melotts-english/model_farm_melotts_en_woman_qcs8550_qnn231_fp16_aidlite/models -i 15
