Silero VAD 模型文件不存在

Error message

Silero VAD 模型文件不存在

What it means

FileNotFoundException thrown in SileroVadDetector's constructor when the ONNX model file at BgiOnnxModel.SileroVad.ModalPath does not exist. ModalPath resolves via Global.Absolute(@"Assets\Model\Vad\silero_vad.onnx") — the file ships as an asset and must be present beside the executable. Missing it means the deployment is incomplete.

Solutions

1. Re-download/re-extract the release so Assets/Model/Vad/silero_vad.onnx exists next to the executable.
2. Launch the app from its own directory so Global.Absolute resolves correctly.
3. Add an antivirus exclusion for the app folder (onnx models are sometimes flagged).
4. Verify the file is included in the .csproj as Content with CopyToOutputDirectory.
5. Run a fresh build; confirm the file appears in bin/<config>/netX.X-windows/Assets/Model/Vad/.

Example fix

// before
var modelPath = BgiOnnxModel.SileroVad.ModalPath;
if (!File.Exists(modelPath))
    throw new FileNotFoundException("Silero VAD 模型文件不存在", modelPath);

// after: clear message with resolved path for diagnostics
var modelPath = BgiOnnxModel.SileroVad.ModalPath;
if (!File.Exists(modelPath))
    throw new FileNotFoundException(
        $"Silero VAD 模型文件不存在：{modelPath}。请确认程序目录下 Assets/Model/Vad/silero_vad.onnx 完整。", modelPath);

var modelPath = BgiOnnxModel.SileroVad.ModalPath;
if (!File.Exists(modelPath))
    return Result.Fail($"缺少模型文件 {modelPath}，语音跳过检测不可用");

try { vad = new SileroVadDetector(); }
catch (FileNotFoundException) { /* disable voice detection, fall back to silent skip */ }

When it happens

Trigger: Constructing a SileroVadDetector (via DialogueOptionVoiceDetector.Create) when Assets/Model/Vad/silero_vad.onnx was not copied to the output directory, was deleted by an antivirus, or the working directory is wrong so Global.Absolute resolves to a non-existent path.

Common situations: Build output cleaned/published without the Assets folder; running the exe from a different working directory; antivirus quarantined the .onnx; partial git checkout excluding large binary assets; extracted a release zip incompletely.
