Are there programming languages designed to use only speech for input?

I am interested in developing a domai开发者_运维百科n-specific language which could be driven only by speech input. Are there examples of programming languages designed specifically for speech-only input? We can assume some form of feedback and storage (for humans), probably a screen although I'd also be interested in languages which have no feedback. I'd be interested in both formal grammars and natural language input.

Perligata is highly pronounceable (http://www.csse.monash.edu.au/~damian/papers/HTML/Perligata.html)

 use Lingua::Romana::Perligata;

    maximum inquementum tum biguttam egresso scribe.
    meo maximo vestibulo perlegamentum da.
    da duo tum maximum conscribementa meis listis.

    dum listis decapitamentum damentum nexto
    fac sic
            nextum tum novumversum scribe egresso.
            lista sic hoc recidementum nextum cis vannementa da listis.
    cis.
