For high-accuracy systems, provide a facility for choosing among alternative decodings.

1. Provide close-scoring alternatives for the user to chose from.

   Most systems can provide alternative decodings (though they typically will act immediately on the best-scoring one).

2. Provide a controlled selection mode to ensure rapid convergence to the correct decoding.
   • Use either an alternate modality (such as a menu) or a restricted sub-language to achieve this goal.
