Lingua is an application developed for the Church of Jesus Christ of Latter-day Saints that performs both real-time interpretation of live speeches and automatic video dubbing (AVD). Like other AVD systems, it can perform synchronized automatic dubbing, given video files and optionally, corresponding text files using a traditional ASR–MT–TTS pipeline. Lingua’s unique contribution is that it can also operate in real-time with a slight delay of a few seconds to interpret live speeches. If no source-language script is provided, the translations are exactly as recognized by ASR and translated by MT. If a script is provided, Lingua matches the recognized ASR segments with script segments and passes the latter to MT for translation and subsequent TTS. If a human translation is also provided, it is passed directly to TTS. Lingua switches between these modes dynamically, enabling translation of off-script comments and different levels of quality for multiple languages. (see extended abstract)

The Church of Jesus Christ of Latter-day Saints undertook an extensive effort at the beginning of this year to deploy machine translation (MT) in the translation workflow for the content on its principal website, www.lds.org. The objective of this effort is to reduce by at least 50% the time required by human translators to translate English content into nine other languages and publish it on this site. This paper documents the experience to date, including selection of the MT system, preparation and use of data to customize the system, initial deployment of the system in the Church’s translation workflow, post-editing training for translators, the resulting productivity improvements, and plans for future deployments.

At AMTA 2002, we reported on a pilot project to machine translate Microsoft’s Product Support Knowledge Base into Spanish. The successful pilot has since resulted in the permanent deployment of both Spanish and Japanese versions of the knowledge base, as well as ongoing pilot projects for French and German. The translated articles in each case have been produced by MSR-MT, Microsoft Research’s data-driven MT system, which has been trained on well over a million bilingual sentence pairs for each target language from previously translated materials contained in translation memories and glossaries. This paper describes our experience in deploying this system and the (positive) customer response to the availability of machine translated articles, as well as other uses of MSR-MT either planned or underway at Microsoft.

MSR-MT is an advanced research MT prototype that combines rule-based and statistical techniques with example-based transfer. This hybrid, large-scale system is capable of learning all its knowledge of lexical and phrasal translations directly from data. MSR-MT has undergone rigorous evaluation showing that, trained on a corpus of technical data similar to the test corpus, its output surpasses the quality of best-of-breed commercial MT systems.

Translation systems that automatically extract transfer mappings (rules or examples) from bilingual corpora have been hampered by the difficulty of achieving accurate alignment and acquiring high quality mappings. We describe an algorithm that uses a best-first strategy and a small alignment grammar to significantly improve the quality of the mappings extracted. For each mapping, frequencies are computed and sufficient context is retained to distinguish competing mappings during translation. Variants of the algorithm are run against a corpus containing 200K sentence pairs and evaluated based on the quality of resulting translations.
