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.
AutoML Translation for highly specialized or technical content. By training it on your own data, you'll get the most accurate translations possible for your specific domain or industry.
AutoML Translation
AutoML Translation enables you to create custom translation models tailored to your specific domain or use case, no coding required.
It utilizes machine learning to analyze your provided translated text pairs and develop a model that can translate new content in the same domain with a higher degree of accuracy than the standard Google pre-trained model.
It seamlessly integrates with Cloud Translation API and Translation Hub service for a smooth workflow orchestration.
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 Contact Center AI (CCAI) 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.

Train a custom translation model
No-code translation model training with AutoML
Access AutoML translation capabilities via Cloud Translation - Advanced to build custom models. It retains all future model enhancements, and the models you build remain available to you across Translation API and Translation Hub advanced tier services.
With no coding, you use your domain-specific datasets (pairs of segments in the source and target languages) to finetune Google’s pretrained model for higher accuracy. Your data remains yours and will not be used to train Google models.

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, Contact Center AI (CCAI) works with the Translation API to deliver a seamless communication across online chat and phone calls.
During a phone call, CCAI 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 CCAI 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.
