An FST is a type of finite-state automaton (FSA) that maps between two sets of symbols. [1] An FST is more general than an FSA. An FSA defines a formal language by defining a set of accepted strings, while an FST defines a relation between sets of strings.
With the advancement of neural networks in natural language processing, it became less common to use FST for morphological analysis, especially for languages for which there is a lot of available training data. For such languages, it is possible to build character-level language models without explicit use of a morphological parser. [1]
Foma is a free and open source finite-state toolkit created and maintained by Mans Hulden.It includes a compiler, programming language, and C library for constructing finite-state automata and transducers (FST's) for various uses, most typically Natural Language Processing uses such as morphological analysis.

The library and utilities are written in C++, with an interface to the library in Python and a utility for looking up results from transducers ported to Java and Python. Transducers in HFST may incorporate weights depending on the backend. For performing FST operations, this is currently only possible via the OpenFST backend.

A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another. [1] Transducers are often employed at the boundaries of automation, measurement, and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.).
I disagree. Mealy machines are a particular kind of transducer, contrasted with Moore machines. For some applications (e.g. speech recognition) the Mealy interpretation is most common, but for others (e.g. bioinformatics) the Moore machine view is more common, and the word "transducer" is more commonly used than either Moore or Mealy machines.
