+SherpaONNX WebAssembly (WASM) runtime setup for AsTeRICS-Grid
+
+This folder is where you can place the SherpaONNX TTS WASM assets to enable the "SherpaONNX (WASM)" provider in the browser.
+
+Required files (place both in this directory):
+- sherpaonnx.js   (WASM glue script)
+- sherpaonnx.wasm (WASM binary)
+
+How to obtain the files:
+- See the official project and web TTS examples:
+  - https://github.com/k2-fsa/sherpa-onnx
+  - Web TTS demo paths typically include files named like above
+
+Notes:
+- Our app passes wasmBaseUrl: "app/vendor/sherpa-onnx" to the js-tts-wrapper client. The runtime will auto-load sherpaonnx.js and resolve sherpaonnx.wasm from this folder.
+- Voice list: the engine fetches models from app/data/merged_models.json by default here (we added a minimal file to get you started). You can replace it with your own.
+
+Troubleshooting:
+- Ensure that sherpaonnx.wasm is served with correct MIME type (application/wasm).
+- If you want to host the assets elsewhere, set wasmBaseUrl or wasmPath in the SherpaONNX provider settings once we expose those in the UI (coming soon), or adjust defaults in voiceProviderService.

-# Tools and libraries
-This chapter is about tools, libraries and technologies that are used in AsTeRICS Grid project:
-
-1. [Tools](02_tools.md#tools)
-1. [Javascript libaries](02_tools.md#javascript-libraries)
-
-[Back to Overview](README.md)
-
-## Tools
-This section is about tools that are used for development, dependency management and releasing.
-
-### Node package manager (npm)
-The [node package manager (npm)](https://www.npmjs.com/) is used for managing Javascript dependencies and running various tasks related to the project. The npm configuration file is [package.json](https://github.com/asterics/AsTeRICS-Grid/blob/master/package.json).
-
-#### npm dependencies
-The configuration file [package.json](https://github.com/asterics/AsTeRICS-Grid/blob/master/package.json) includes the key `dependencies` which include dependencies that are used in order to run AsTeRICS Grid:
-* **[@klues/couch-auth](https://github.com/perfood/couch-auth)**: framework providing user management in connection to [CouchDB](http://couchdb.apache.org/), the database backend used by AsTeRICS Grid. Using fork of original [couch-auth](https://github.com/perfood/couch-auth) in order to fix [session creation conflicts](https://github.com/perfood/couch-auth/issues/65) - already merged, so we could again use original `couch-auth`
-* **[cors](https://www.npmjs.com/package/cors)**: CORS handler for HTTP requests, used by couch-auth
-* `dotenv-flow`: used by `superlogin/start.js`
-* `express`: used by `superlogin/start.js`
-* `file-saver`: used for `download backup to file` feature
-* `hls.js`: used for playback of special audio streams for web-radio and podcast features
-* `html2canvas`: used for creating thumbnail screenshots of grids
-* `interactjs`: used by [vue-css-grid-layout](https://github.com/asterics/vue-css-grid-layout) library (this library is not used as npm dependency, but the code is duplicated in folder `src/vue-components/grid-layout`)
-* `jspdf`: used by PDF export feature
-* `jszip`: used for importing/exporting OBZ files from [Open Board Format](https://www.openboardformat.org/docs)
-* `matrix-encrypt-attachment`: used for [Matrix](https://matrix.org/) messenger integration
-* `matrix-js-sdk`: used for [Matrix](https://matrix.org/) messenger integration
-* **[morgan](https://www.npmjs.com/package/morgan)**: logger for HTTP requests, used by couch-auth
-* `n-ary-huffman`: used for Huffman input method
-* `navigo`: used for in-app routing, see `router.js`
-* `pouchdb`: library for connecting with external CouchDB - the npm dependency is used by `superlogin/start.js`, the app uses the direct import in `index.html`, see below.
-* `predictionary`: library for self-learning dictionary used for keyboard inputs, also see dictionaries at `app/dictionaries`
-* **[superlogin-client](https://www.npmjs.com/package/superlogin-client)**: Javascript client for a couch-auth instance running on a server
-* **[vue](https://vuejs.org/)**: framework for building the user interface
-* `vue-i18n`: internationalization library for Vue.js
-* `vue-multiselect`: multiselect component, used for selecting tags in word forms feature
-
-Also see other directly imported [Javascript libraries](02_tools.md#javascript-libraries).
-
-#### npm dev-dependencies
-The configuration file [package.json](https://github.com/asterics/AsTeRICS-Grid/blob/master/package.json) includes the key `dev-dependencies` which include dependencies that are used for development of AsTeRICS Grid. These are the most important ones:
-* **[webpack](https://www.npmjs.com/package/webpack)**: framework using for bundling javascript, vue and css resources
-* **[webpack-dev-server](https://www.npmjs.com/package/webpack-dev-server)**: local http server for development of the application
-* **[babel-core](https://www.npmjs.com/package/babel-core)**: framework for transpiling Javascript sources with newer language features to Javascript that is compatible with older browsers.
-* **[jest](https://www.npmjs.com/package/jest)**: Unit testing framework for javascript
-
-#### npm scripts
-
-A description of [available npm scripts is available in README.md](https://github.com/asterics/AsTeRICS-Grid/tree/master?tab=readme-ov-file#npm-scripts).
-
-### Webpack
-
-[Webpack](https://webpack.js.org/) is used in order to bundling the Javascript sources to a single and minified bundle file. The configuration file for webpack is [webpack.config.js](https://github.com/asterics/AsTeRICS-Grid/blob/master/webpack.config.js).
-
-## Javascript libraries
-This section is about Javascript libraries that are used within the AsTeRICS Grid project and are imported directly in `index.html` and not via `npm`. All directly imported libraries are located at [app/lib/](https://github.com/asterics/AsTeRICS-Grid/tree/master/app/lib).
-
-These are the Javascript libraries that are directly imported:
-* **[dom-i18n](https://github.com/ruyadorno/dom-i18n)**: easy to use DOM-internationalization library
-* **[jQueryUI](https://jqueryui.com/)**: library for user interface interactions, needed for jQuery contextMenu and GridList
-* **[jQuery contextMenu](https://swisnl.github.io/jQuery-contextMenu/)**: jQuery plugin for right-click context menus, used in AsTeRICS Grid e.g. for edit menu of a grid element
-* **[jQuery](https://jquery.com/)**: library for document traversal and manipulation, needed for jQueryUI
-* **[loglevel](https://github.com/pimterry/loglevel)**: javascript logging library
-* **[modernizr](https://github.com/Modernizr/Modernizr)**: for testing availability of JS features and redirect to `unsupported.html` if needed, see [checks in index.html](https://github.com/asterics/AsTeRICS-Grid/blob/master/index.html#L111)
-* **[ObjectModel](https://objectmodel.js.org/)**: library for dynamic type checking, see data models in [src/js/model/](https://github.com/asterics/AsTeRICS-Grid/tree/master/src/js/model) - should be replaced by ES6 classes or TypeScript at some point.
-* **[PouchDB](https://pouchdb.com/)**: library for accessing [IndexedDB](https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API) and synchronization with a remote [CouchDB](http://couchdb.apache.org/)
-* **[responsive-voice](https://responsivevoice.org/)**: library for interacting with responsive voice service, generating TTS samples
-* **[sjcl](https://github.com/bitwiseshiftleft/sjcl)**: crypto library published by Stanford University that is used for encryption of user configuration
-* **[uart.min.js](https://github.com/asterics/EspruinoWebTools/blob/master/uart.js)**: library for interacting with WebSerial and WebBluetooth APIs, used for UART action.
