Speech-Over Professional is a voice input and output program, audio file creation program, and captioning system designed to add audio content to Microsoft PowerPoint presentations. This program offers a text-to-speech feature to add speech to selected sections of text with a simple dialog that allows the user to enter the text to be spoken and choose the voice to speak it. The dialog can also be used to add speech to graphics. A male and female voice are included. Text can be typed in or dictated, and the clips are played in sequence in the slide show. Additionally, the user can import a sound file or record his or her own voice instead of using text-to-speech for the narration. Using Speech-Over Professional, a person can write formatted narration clip text to the PowerPoint notes pane in the order the clips are played in the presentation as well as importing existing notes from the PowerPoint notes pane for narration clip text. Speech-Over Professional also creates subtitles for each narration clip. Subtitles are displayed automatically in coordination with the narration. Subtitles that are too long to fit on the screen are automatically subdivided and displayed in succession, synched with the voice. The subtitle font size can be enlarged for visually-impaired viewers. The program's SAPI voice editor allows the user to modulate, adjust and fine-tune the text-to-speech voice by introducing delays, changing pitch, speed and volume, and adding emphasis within the flow of the speech. Using the Edit dialog, the user can also edit existing individual narration clips and edit the text for all narration clips on a slide at one time with the program's Slide Clip Text Editor. In addition to U.S. English, Speech-Over Professional is available with voices speaking UK English, Indian English, Danish and German. COMPATIBILITY: For use with IBM computers running Microsoft Windows. SYSTEM REQUIREMENTS: Microsoft Windows XP, Vista or Windows 7; Microsoft Office XP/2003, 2007 or 2010.
