The 8-bit uLaw to 16-bit PCM and the 13-bit-PCM to 8-bit uLaw
tables were lifted from the rsynth-2.0 sources. The README says:
This is a text to speech system produced by integrating various pieces
of code and tables of data, which are all (I believe) in the public domain.
The bulk of the intergration was done by myself, that is Nick Ing-Simmons.
I can be reached via my employer at nik@tiuk.ti.com.
