As businesses increasingly look to expand their global reach, the demand for high-quality, accurate translations has never been higher. At Microsoft, we’re committed to providing the most powerful and effective translation tools available, and we’re excited to announce the latest upgrade to our Custom Translator platform.
In recent years, Custom Translator was upgraded to state-of-the-art Transformer architecture as part of our ongoing effort to improve our custom translation and provide the best possible translation quality to our customers. The upgrade was done in two phases, first phase was completed in November 2020 and second phase was completed in August 2022.
And today, we unveiled a significant upgrade to our platform. In this blog post, we will explore the model quality trained on the new Custom Translator platform.
Custom Translator platform’s latest upgrade is still based on the Transformer architecture; however, our team of experts have been hard at work developing a new set of algorithms and techniques, grounded by customer feedback and testing, to improve the accuracy and quality of Custom Translator models when adapted to customer terminology and domain data. Thanks to these enhancements, customers can now expect more accurate translations than previous models.
To put it to the test, we conducted a series of customer evaluations on Custom Translator’s upgraded models. Five customers participated, covering German, Spanish, French, Japanese and Chinese in different business domains. The results were impressive, with significant improvements in translation quality.
The chart below shows the average improvement from the customer evaluations.
The blue solid bars show the average improvement across language pairs when comparing our strong general models to the new Custom Translator platform adapted to the customer domain terminology and data. Across the five customers and five languages, there is a 4.3 BLEU improvement of the custom models over our strongest general models. For customers with parallel data, using Custom Translator provides even higher quality translation than our general systems.
The striped green bars show the average improvement across language pairs when comparing the new Custom Translator system adapted to the customer data to the previous version of Custom Translator. Across the five customers and five languages, there is a 4.5 BLEU improvement. For customers already using Custom Translator, the new platform upgrade provides an even larger improvement.
We’re thrilled to offer this upgrade to customers and we’re confident it will help businesses around the world communicate more effectively and efficiently. Custom Translator is now even more powerful and effective than ever before.
