vosklet's Issues

Error: "Unable to open tar in WASM memory" using en-model.tgz

Getting this using en-model.tgz served from my webserver with the latest

Vosklet/src/genericModel.cc

Line 14 in ef01094

fireEv(index, "Unable to open tar in WASM memory");

ReferenceError: Can't find variable: SharedArrayBuffer

[Error] Unhandled Promise Rejection: ReferenceError: Can't find variable: SharedArrayBuffer
	(anonymous function) (Vosklet.js:9:9494)
	(anonymous function) (index.html:21)

Safari Version 17.3.1 (19617.2.4.11.12)

Happens after clicking start and speaking via the example

Thanks for the lib, still failing to get browser offline speech recognition working with any example from any offering 🙃

evaluation give worse metrics then server-based VOSK. Way to run it sync for test?

I have a dataset of syllables on which I perform the evaluation.
Each wav = 1 syllable (0.2 sec). Just read one by one, recognize, check with ground true.

Vosk on the host gives ~80% accuracy.

Vosklet give ~65%, Possible it's because async nature of the js wrapper.
I use a timeout 2 sec to divide different wav recognition, but 11% of records have nothing as recognized result, and 8% contains 2 syllables.

Other things all the same between hosted Vosk and browser Vosklet.
Maybe running in main thread synchronously will help?

"TypeError: cannot convert undefined to object" in VoskletTransferer

Sometimes, VoskletTransferer will throw a TypeError: cannot convert undefined to object exception immediately after initialization. It won't always happen right away, but usually will after a few reloads. It seems there is a race condition between the connection of the source and processor nodes and the execution of VoskletTransferer's process method.

The error is being thrown here:

Vosklet/src/wrapper.js

Line 11 in 76aedbd

this.buffer.set(inputs[0][0], this.count * 128)

Adding a falsiness check here should fix it:

const data = inputs[0][0]
if (!data) return true
this.buffer.set(data, this.count * 128)

Error when loading Vosklet

The error
UncaughtReferenceError: SharedArrayBuffer is not defined at Vosklet.js:9:9648

Import via module: Can't find variable window

I've installed the library via NPM and load with import loadVosklet from 'vosklet';

Get the following error running the demo code from the readme

working example?

I tried to run on IDE devserver, different services but get error about SharedBufferArray
I created a simple Flask with necessary CORS headers, but now it fails at

let model = await module.createModel("en-model.tgz","model","ID")

with

Uncaught (in promise) TypeError: Failed to fetch

Not work with different model

On the step of model's creation (malloc) JS throw error without text but with 1 number, it looks like number of bytes tried to allocate.

Have you built model with fixed memory size? doesn't it allow memory_grow?
