Why Offer both Speech and DTMF Commands?
Your assistant accepts both speech commands and DTMF (Touch-tone) commands. Note that some installations support only DTMF commands or only speech commands. Both of these telephone user interfaces (TUI) enable you to perform the same set of functions but using different methods. The DTMF mode is useful in noisy environments or when discretion is needed. The speech interface is more practical for people driving and using hands-free phone sets. Users can switch back and forth between these dialog modes with a single command.
DTMF Commands for Navigation
- STAR(*) is commonly used to CANCEL a command or to go back to the previous menu level.
- POUND(#) is commonly used to CONFIRM something or SKIP an option offered.
- TYPE-AHEAD is supported for most menus enabling you to enter one, two or three DTMF commands separated by very short pauses without having to wait for prompts to play.
- BARGE-IN is also supported enabling you to enter your DTMF commands while prompts or messages are being played. The play is interrupted as soon as you press a DTMF key.
Enter your Contact Names using DTMF Keys
Name spelling using DTMF keys is supported. You simply press the DTMF key on which the letter is located. Here is the DTMF mapping to letters of the alphabet:
Press 2 for A, B or C
Press 3 for D, E or F
Press 4 for G, H or I
Press 5 for J, K or L
Press 6 for M, N or O
Press 7 for P, Q, R or S
Press 8 for T, U or V
Press 9 for W, X, Y or Z
Here are some guidelines about the spelling of contact names using DTMF keys:
- Do not enter any special characters such as the space between the last and first name or dashes (-) in composed names;
- Do not enter any middle name or initial;
- Use English-equivalents to any foreign language letters. For example, use E for É, È or Ê.
