Translation AI
Accelerate global growth with quality translation at scale, powered by Gemini
Translate websites, apps, documents, and media across 189 languages. You can leverage pre-trained and custom translation models instantly, as well as achieve nuanced accuracy with Gemini-powered Adaptive Translation, all through Cloud Translation API.
Overview
Adaptive translation
Adaptive Translation helps you create nuanced, high-quality translations that capture the unique style, tone, and voice of your content. By combining the power of large language models (LLMs) with your own small datasets, Adaptive translation delivers results that are often on par with custom-built models – but without the complexity of training or maintaining them.
Here are the languages supported by Adaptive Translation.
Cloud Translation API
Cloud Translation API uses Google's neural machine translation technology to let you dynamically translate text through the API using a Google pre-trained, custom model, or a translation specialized large language model (LLMs).
It comes in Basic and Advanced editions. Both provide fast and dynamic translation, but Advanced offers customization features, such as domain-specific translation, formatted document translation, and batch translation.
The first 500,000 characters sent to the API to process (Basic and Advanced combined) per month are free (not applicable to LLMs).
Model selection
For advanced translations, you're not limited to a one-size-fits-all solution, ensuring the highest quality and accuracy for your specific content. You can choose from the following models, based on your needs:
Neural Machine Translation (NMT) for general text in everyday use cases like website content or news articles.
Translation Large Language Model (LLM) for conversational text like messages or social media posts. You can use "Adaptive" mode to fine-tune translations based on your own examples for an even closer match to your unique style.
Media file translation, subtitling and voice-over solutions
For a simple translated transcript of a video or audio, Speech-to-text API transcribes your video or audio with high accuracy into a text file that can be translated by the Translation API into different languages.
To subtitle your videos after transcription and translation, use Transcoder API to add subtitles.
To voice-over your videos in different languages, transcribe and translate, then use Cloud Text-to-speech API to synthesize custom, lifelike speech in 380+ voices across 50+ languages.
Multilingual contact center solution for global markets
Combining Customer Engagement Suite and Translation API allows you to assist a customer interaction happening in two different languages seamlessly across phone and chat, all in real-time. CCAI helps break language barriers by natively supporting both customer sentiment and call driver analysis, across many different languages. These analyses can be fed back to agents, in their preferred language, for better call outcomes and customer experience.
Data privacy and security
Google Cloud has industry-leading capabilities that give you—our customers—control over your data and provide visibility into when and how your data is accessed.
As a Google Cloud customer, you own your customer data. We implement stringent security measures to safeguard your customer data and provide you with tools and features to control it on your terms. Customer data is your data, not Google’s. We only process your data according to your agreement(s).

Common Uses
Translate a website or app
Programmatically translate your site and app with scale
To translate long form content on your website or in your app, with consistency and higher level of accuracy, use Cloud Translation API - Advanced. Otherwise, use Cloud Translation API - Basic for simplicity and scale.
Create a Google Cloud project with the API enabled to use the service, then install client libraries for common programming languages to make calls to the API. With Advanced edition, you can use glossaries, custom translation models, and batch translate for efficiency.
First 500,000 characters sent to Cloud Translation API for processing every month are free.

Subtitle a video in different languages
Subtitle at scale with Google Cloud APIs
Use Cloud Speech-to-text API and Cloud Translation API to subtitle your videos in different languages at the same time. Store the videos you’d like to subtitle in Cloud Storage. Cloud Speech-to-text API then transcribes your video with accuracy and supports speech recognition in 145 languages. Cloud Translation API takes the transcription output (plain text and srt files) and translates into up to 130+ languages. The translated files can then be uploaded to your video for subtitles to show up.
Both APIs have a free tier that allows you to use the products for free up to monthly limits.

Dub a video in different languages
Dub your video with AI
Dubbing a video in a foreign language requires Cloud Speech-to-Text, Translation, and Text-to-Speech APIs. Speech-to-Text API’s transcription of your video gets translated into desired languages by the Translation API; then Text-to-Speech API generates audio from the translated text.
All the APIs’ performance can be enhanced with a custom or domain-specific model. For example, Text-to-Speech API can create unique and natural-sounding voices for your organization with a custom voice model.

Translation-aided customer interactions
Translate customer interactions in real time with CCAI
When your customers and agents speak different languages, Customer Engagement Suite works with the Translation API to deliver a seamless communication across online chat and phone calls.
During a phone call, Customer Engagement Suite transcribes what the customer says, the Translation API translates it into the agent’s preferred language in real time, the agent replies in their language, which gets translated back into the customer’s language, and Customer Engagement Suite delivers the translated response in synthesized speech.
Agent Assist, under the CCAI solution, works with the Translation and other APIs to enable this use case.
