Finite State Transducer:

• A deterministic finite transducer is indeed a deterministic finite state automata that includes either an inputs as well as an output sequence..

• It turns every input file to something like a string output..

The following seems to be the precise definition of a State Machine Transducer (FST):

A Finite State Transducer (FST) is a 6-tuple machine with the following representation:$M=\left(Q,∑,r,\mathrm{δ},q_0\right)$where

• Q is a finite set of states.

• $∑$ is a finite set of input alphabets.

• r is a finite set of output alphabets.

• $\mathrm{δ}:Qx∑→QxT$is the transition function that defines rules.

• $q_0∈Q$, is the start state.

The proper definition for Finite State Transducer (FST) computing seems to be as follows:

•This finite state machine gets computed by converting the input stream into an output string.

• Suppose w is really a string that spans the source alphabet. $∑$where x is very much an output string made out of the letters of the alphabet r .

• This changeover takes place in a series of states. $q_0,q_1,q_2,...q_{n}inQ$ such that $q_0=q_0$
