VAD-WEB error on safari : SIMD not supported in the current environment

[Serotoninene]

Description

I'm using the MicVAD library for voice activity detection, and it works well in Chrome. However, when I try to run it in Safari, I get an error indicating that "SIMD is not supported in the current environment".

Complete error : "no available backend found. ERR: [wasm] Error: WebAssembly SIMD is not supported in the current environment., [cpu] Error: previous call to 'initWasm()' failed"

Code Snippet

Here’s a simplified version of how I am initializing MicVAD:

 this.myvad = await vad.MicVAD.new({
    positiveSpeechThreshold: 0.9,
    onFrameProcessed: (frame) => {
      if (!this.micAccessConfirmed) {
        this.micAccessConfirmed = true;
        this.connected();
      }
    },
    onSpeechStart: () => {
      if (!this.isConnected) return;
      this.toListening();
    },
    onSpeechEnd: (audio) => {
      this.isListening = false;
      this.toProcessing(audio);
    },
    redemptionFrames: 10 * 1.4,
  });

I would like to know if there is a way to use MicVAD or a fallback approach when SIMD is not supported by the browser.

Environment

• vad-web version : @0.0.7

Hi @Serotoninene can you share what version of onnxruntime-web you are using?

Hi @ricky0123 ! I'm not sure, I followed your doc and used those scripts :

<script src="https://cdn.jsdelivr.net/npm/onnxruntime-web/dist/ort.js"></script>
<script src="https://cdn.jsdelivr.net/npm/@ricky0123/[email protected]/dist/bundle.min.js"></script>

After doing some research, I found out that SIMD wasn't supported in Safari prior to version 16. Is there any way to make it work on older versions, or is it simply not feasible?

[ricky0123]

Hi @Serotoninene can you try using an older version of onnxruntime-web? You can try these script tags

<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/ort.js"></script>
<script src="https://cdn.jsdelivr.net/npm/@ricky0123/[email protected]/dist/bundle.min.js"></script>

I also encountered the same problem. I think it may be caused by the problem described in: 15644. I tried to follow the possible solutions mentioned there, but I couldn't complete it, so I'm not sure if it works. I want to know if Ricky has a good way to solve or avoid it.

My usage scenario is in the ionic capacitor project, and my js part of the code runs in the webview, so I am also affected by the iOS webviewb version and defects

Hi all, can you test using the most recent version of the library?

Hi all, can you test using the most recent version of the library?

I have upgraded to the latest version, which solves the problem that versions below iOS 16.5 cannot be used. Thank you very much for your help.
