La característica de reconocimiento de texto de la API de Cloud Vision puede detectar una gran variedad de idiomas, incluso en una sola imagen.
No es necesario proporcionar una sugerencia de idioma al servicio, pero es posible hacerlo si este tiene problemas para detectar el idioma que se usa en la imagen.
Con el lanzamiento de OCR de escritura a mano disponible al público general, las imágenes que tienen escritura a mano ya no requieren una marca de escritura a mano languageHints cuando se usa DOCUMENT_TEXT_DETECTION.
Las sugerencias de idioma opcionales se especifican en el ImageContext de una solicitud como una lista de languageHints para una solicitud DOCUMENT_TEXT_DETECTION y TEXT_DETECTION.
Por lo general, cada parámetro del código de idioma consta de un identificador BCP-47. Este parámetro puede tener el formato idioma-región, en el que el idioma se refiere al idioma principal, y la región opcional se refiere a una región (por lo general, un identificador de país) con un dialecto determinado. Por ejemplo, el chino puede representarse como chino simplificado, que se usa en la República Popular China (zh-Hans), o como chino tradicional, que se usa en Taiwán (zh-Hant).
Existen tres niveles de compatibilidad de idiomas en la función de reconocimiento de texto:
- Los idiomas compatibles son los que priorizamos y con los que evaluamos el rendimiento de forma periódica.
- Los idiomas experimentales son aquellos que se encuentran en desarrollo activo, pero que no se evalúan con regularidad.
- Los idiomas asignados son aquellos que pueden asignarse a otro código de idioma o a un reconocedor de caracteres general. Por ejemplo, “
en-GB” es compatible, pero no se trata de manera diferente a “en” para reconocer texto. Nos esforzamos por mostrar el código de idioma asignado correcto en el campo de configuración regional de la entidad, pero los idiomas asignados tienen más probabilidades de identificarse de manera errónea como idiomas similares que los completamente admitidos o los experimentales.
A continuación, se muestra la lista de idiomas (con códigos languageHint asociados) compatibles con TEXT_DETECTION y DOCUMENT_TEXT_DETECTION.
Si la sugerencia de idioma se deja en blanco, intentaremos detectar de forma automática el idioma más apropiado. El extremo TEXT_DETECTION detectará de manera automática solo un subconjunto de idiomas compatibles, mientras que el extremo DOCUMENT_TEXT_DETECTION detectará automáticamente el conjunto completo de idiomas compatibles.
