Query: A Configurable Multilingual Model is All You Need to Recognize All
  Languages   Multilingual automatic speech recognition (ASR) models have shown great
promise in recent years because of the simplified model training and deployment
process. Conventional methods either train a universal multilingual model
without taking any language information or with a 1-hot language ID (LID)
vector to guide the recognition of the target language. In practice, the user
can be prompted to pre-select several languages he/she can speak. The
multilingual model without LID cannot well utilize the language information set
by the user while the multilingual model with LID can only handle one
pre-selected language. In this paper, we propose a novel configurable
multilingual model (CMM) which is trained only once but can be configured as
different models based on users' choices by extracting language-specific
modules together with a universal model from the trained CMM. Particularly, a
single CMM can be deployed to any user scenario where the users can pre-select
any combination of languages. Trained with 75K hours of transcribed anonymized
Microsoft multilingual data and evaluated with 10-language test sets, the
proposed CMM improves from the universal multilingual model by 26.0%, 16.9%,
and 10.4% relative word error reduction when the user selects 1, 2, or 3
languages, respectively. CMM also performs significantly better on
code-switching test sets.
