Neural Machine Translation model

The Translation API's recognition engine supports a wide variety of languages for the Neural Machine Translation (NMT) model.

These languages are specified within a recognition request using language code parameters as noted on this page. Most language code parameters conform to ISO-639 identifiers, except where noted.

Translations from any language to any language in this list are supported. Romanization and transliteration are supported only on the Cloud Translation - Advanced API. The list is updated as new languages are added. You can also list the supported languages by using Cloud Translation - Basic or Cloud Translation - Advanced APIs.

Try it for yourself

If you're new to Google Cloud, create an account to evaluate how Cloud Translation performs in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

Custom models

For Cloud Translation - Advanced, AutoML Translation supports the following language pairs for custom models. A supported language means that Google has an existing Neural Machine Translation (NMT) model for that language, which AutoML Translation uses as a base to create a custom model during training.

Supported codes for language variants

The following language codes are variants of the supported languages in the previous table. You can use these codes as the source or target language when you create datasets.

Google doesn't have base NMT models for these languages. Instead, Cloud Translation uses the language variant's associated base model for training custom models.

These codes are useful, for example, when you translate content for a particular dialect or region. For example, suppose you have localized data for zh-HK that you create a custom model for. When you perform translations, you can specify the zh-HK language code, which points to your custom model and produces more accurate translations for that locale.

The following table lists the language codes, their descriptions, and their associated base models that Cloud Translation uses when training custom models.

Language code	Description	Base model
zh-HK	Hong Kong (Traditional)	zh-TW
