Problem

Hi! I implemented QNN support and prepared the app flow, but I cannot validate it end-to-end because I do not have a compatible Snapdragon device.

I would really appreciate help from someone with a QNN-capable Android phone to run a quick verification.

What I need tested

1. Check if QNN is available on the device.
2. Run STT with provider: "qnn".
3. Confirm whether initialization and transcription succeed.
4. Share logs/output + device details.

1) QNN availability check snippet

import {
  getQnnSupport,
  getDeviceQnnSoc,
  getAvailableProviders,
} from 'react-native-sherpa-onnx';
export async function debugQnnAvailability() {
  const [qnn, soc, providers] = await Promise.all([
    getQnnSupport(),
    getDeviceQnnSoc(),
    getAvailableProviders(),
  ]);
  console.log('QNN support:', qnn);
  // qnn shape: { providerCompiled, hasAccelerator, canInit }
  console.log('Device SoC:', soc);
  // soc shape: { soc: string | null, isSupported: boolean }
  console.log('Available ORT providers:', providers);
  // Example: ["CPU", "NNAPI", "QNN", "XNNPACK"]
}

Expected for a good QNN device:

qnn.canInit === true
providers contains "QNN"
soc.isSupported === true (SM8xxx)

2) STT with QNN snippet

import { createSTT } from 'react-native-sherpa-onnx/stt';
export async function testSttQnn() {
  // Replace these paths with your local model/audio paths.
  const modelPath = '/data/user/0/<your.app.id>/files/sherpa-onnx/models/qnn/<your-model-folder>';
  const audioPath = '/data/user/0/<your.app.id>/files/test_audio_16k.wav';
  const stt = await createSTT({
    modelPath: { type: 'file', path: modelPath },
    provider: 'qnn',
    numThreads: 1,
    debug: true,
  });
  try {
    const result = await stt.transcribeFile(audioPath);
    console.log('QNN STT result:', result?.text);
  } finally {
    await stt.destroy();
  }
}

Please include in your reply

• Device model and Android version
• Output of debugQnnAvailability()
• Whether STT init with provider: "qnn" succeeds
• Whether transcription succeeds and sample output text
• Any crash/error stack traces
