Spell checking is done on the fly, either on output or on saving the results:

Output corrected results

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
// Add an image to OcrInput object
Aspose.OCR.OcrInput input = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
input.Add("source.png");
// Recognize image
List<Aspose.OCR.RecognitionResult> results = recognitionEngine.Recognize(input);
// Output corrected result
string correctedResult = results[0].GetSpellCheckCorrectedText(Aspose.OCR.SpellChecker.SpellCheckLanguage.Eng);
Console.WriteLine(correctedResult);

Save corrected results

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
// Add an image to OcrInput object
Aspose.OCR.OcrInput input = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
input.Add("source.png");
// Recognize image
List<Aspose.OCR.RecognitionResult> results = recognitionEngine.Recognize(input);
// Save corrected result
results[0].Save("result.txt", Aspose.OCR.SaveFormat.Text, true, Aspose.OCR.SpellChecker.SpellCheckLanguage.Deu);

Automatic spelling correction requires additional processing resources and is disabled by default.

Spelling correction of any text

You can also correct misspelled words in any text string using CorrectSpelling method of Aspose.OCR.AsposeOcr class:

string text = "Die schönste Jungfrau sitzet dort oben wunderbar";
string correctedText = recognitionEngine.CorrectSpelling(text, Aspose.OCR.SpellChecker.SpellCheckLanguage.Deu);
Console.WriteLine(correctedResult);
