Predicts the language of an input text. **Signature:** export declare class LanguageDetector extends TaskRunner ## Methods | Method | Modifiers | Description | |---|---|---| | [createFromOptions(wasmFileset, textClassifierOptions)](https://developers.google.com/edge/api/mediapipe/js/tasks-text.languagedetector#languagedetectorcreatefromoptions) | `static` | Initializes the Wasm runtime and creates a new language detector from the provided options. | | [createFromModelBuffer(wasmFileset, modelAssetBuffer)](https://developers.google.com/edge/api/mediapipe/js/tasks-text.languagedetector#languagedetectorcreatefrommodelbuffer) | `static` | Initializes the Wasm runtime and creates a new language detector based on the provided model asset buffer. | | [createFromModelPath(wasmFileset, modelAssetPath)](https://developers.google.com/edge/api/mediapipe/js/tasks-text.languagedetector#languagedetectorcreatefrommodelpath) | `static` | Initializes the Wasm runtime and creates a new language detector based on the path to the model asset. | | [setOptions(options)](https://developers.google.com/edge/api/mediapipe/js/tasks-text.languagedetector#languagedetectorsetoptions) | | Sets new options for the language detector. Calling `setOptions()` with a subset of options only affects those options. You can reset an option back to its default value by explicitly setting it to `undefined`. | | [detect(text)](https://developers.google.com/edge/api/mediapipe/js/tasks-text.languagedetector#languagedetectordetect) | | Predicts the language of the input text. | ## LanguageDetector.createFromOptions() {#languagedetectorcreatefromoptions} Initializes the Wasm runtime and creates a new language detector from the provided options. **Signature:** static createFromOptions(wasmFileset: WasmFileset, textClassifierOptions: LanguageDetectorOptions): Promise; ### Parameters | Parameter | Type | Description | |---|---|---| | wasmFileset | WasmFileset | A configuration object that provides the location of the Wasm binary and its loader. | | textClassifierOptions | LanguageDetectorOptions | The options for the language detector. Note that either a path to the TFLite model or the model itself needs to be provided (via `baseOptions`). | **Returns:** Promise\ ## LanguageDetector.createFromModelBuffer() {#languagedetectorcreatefrommodelbuffer} Initializes the Wasm runtime and creates a new language detector based on the provided model asset buffer. **Signature:** static createFromModelBuffer(wasmFileset: WasmFileset, modelAssetBuffer: Uint8Array | ReadableStreamDefaultReader): Promise; ### Parameters | Parameter | Type | Description | |---|---|---| | wasmFileset | WasmFileset | A configuration object that provides the location of the Wasm binary and its loader. | | modelAssetBuffer | Uint8Array \| ReadableStreamDefaultReader | An array or a stream containing a binary representation of the model. | **Returns:** Promise\ ## LanguageDetector.createFromModelPath() {#languagedetectorcreatefrommodelpath} Initializes the Wasm runtime and creates a new language detector based on the path to the model asset. **Signature:** static createFromModelPath(wasmFileset: WasmFileset, modelAssetPath: string): Promise; ### Parameters | Parameter | Type | Description | |---|---|---| | wasmFileset | WasmFileset | A configuration object that provides the location of the Wasm binary and its loader. | | modelAssetPath | string | The path to the model asset. | **Returns:** Promise\ ## LanguageDetector.setOptions() {#languagedetectorsetoptions} Sets new options for the language detector. Calling `setOptions()` with a subset of options only affects those options. You can reset an option back to its default value by explicitly setting it to `undefined`. **Signature:** setOptions(options: LanguageDetectorOptions): Promise; ### Parameters | Parameter | Type | Description | |---|---|---| | options | LanguageDetectorOptions | The options for the language detector. | **Returns:** Promise\ ## LanguageDetector.detect() {#languagedetectordetect} Predicts the language of the input text. **Signature:** detect(text: string): LanguageDetectorResult; ### Parameters | Parameter | Type | Description | |---|---|---| | text | string | The text to process. | **Returns:** LanguageDetectorResult
