DocuMaker Communication Solutions (In Writing!) can transcribe your written material into speech using professional editing and TTS voiceover technology. Using voice synthesis, we can create and submit natural-sounding spoken audio from text in WAV or MP3 format. To ensure quality, we do NOT use the Text To Speech engines from Microsoft. Our voice inventory is much closer to real human speech and our experience in editing text to sound the way that it should makes it difficult to distinguish a human reader from a digitized reader.
