[4.5.0] - 2019-07-10

Speech changes in Web Chat 4.5

This is a breaking change on behavior expectations regarding speech in Web Chat.

In issue #2022, it was brought to the Web Chat team's attention that the speech behavior of v3 and v4 of Web Chat do not match. In the 4.5 release, the expected behavior of a speech bot has been modified in order to bring parity to v3 behavior regarding input hint. This means the following:

• Expecting input will now be respected by Web Chat and open the microphone during a speech conversation. This is assuming that the user has given permission for the browser to use the mic.
• Accepting input will no longer open the mic after the bot has responded to a speech activity from the user. Instead, the user will have to press the microphone button again in order to further interact with the bot.
• Ignoring input will continue to not open the mic after a speech activity has been sent from the bot.
