LanguageDetector
class LanguageDetector : NSObject
@brief Predicts the language of an input text.
This API expects a TFLite model with TFLite Model Metadatathat contains the mandatory (described below) input tensor, output tensor, and the language codes in an AssociatedFile.
Metadata is required for models with int32 input tensors because it contains the input process unit for the model’s Tokenizer. No metadata is required for models with string input tensors.
Input tensor
- One input tensor (
kTfLiteString
) of shape[1]
containing the input string.
Output tensor
- One output tensor (
kTfLiteFloat32
) of shape[1 x N]
whereN
is the number of languages.

Parameters
modelPath
An absolute path to a TensorFlow Lite model file stored locally on the device.
error
An optional error parameter populated when there is an error in initializing the language detector.
Return Value

Parameters
text
The
