Amazon Lex is excited to launch DTMF-only slot settings and configurable session attributes within the Lex console.
Lex now lets you set session attributes to control voice and DTMF input modes. Dual tone multi-frequency (DTMF) is the sound generated when numbers are pressed on a telephone keypad. You can control voice and DTMF configuration for each slot separately for the initial prompt and each retry prompt using the new ‘Advanced Retry’ settings. There is also a new setting: Play the messages in order. This sets the message variations for a slot to play in the order they have been entered instead of randomly. The new DTMF settings are generally available in all AWS regions where Amazon Lex V2 operates. To learn more, read our blog announcing the DTMF slot, watch the training video, or visit the Amazon Lex documentation page.
