1. A voice messaging system for converting an audio voice message from a caller to text, the voice messaging system comprising:
- at least one automatic speech recognition (ASR) resource; and
a computer implemented context sub-system configured to;
use context information about the context of the audio voice message or a part of the audio voice message to limit the vocabulary used by the at least one ASR resource to improve conversion accuracy of the at least one ASR resource in converting at least a portion of the audio voice message to text; and
a text output device that outputs the text to the intended recipient.
