LanguageDetector

public final class LanguageDetector

Predicts the language of an input text.

This API expects a TFLite model with TFLite Model Metadata that contains the mandatory (described below) input tensors, output tensor, and the language codes in an AssociatedFile.

Input tensor
- One input tensor (kTfLiteString) of shape [1] containing the input string.
Output tensor
- One output tensor (kTfLiteFloat32) of shape [1 x N] where N is the number of languages.

Nested Classes

class LanguageDetector.LanguageDetectorOptions Options for setting up a LanguageDetector.

Public Methods

void	close() Closes and cleans up the `LanguageDetector`.
static LanguageDetector	createFromFile(Context context, String modelPath) Creates a `LanguageDetector` instance from a model file and the default `LanguageDetector.LanguageDetectorOptions`.
static LanguageDetector	createFromFile(Context context, File modelFile) Creates a `LanguageDetector` instance from a model file and the default `LanguageDetector.LanguageDetectorOptions`.
static LanguageDetector	createFromOptions(Context context, LanguageDetector.LanguageDetectorOptions options) Creates a `LanguageDetector` instance from `LanguageDetector.LanguageDetectorOptions`.
LanguageDetectorResult	detect(String inputText) Predicts the language of the input text.
