Speech and voice input - Real-time text available

[sydneycolemanfromgoogle]

Is this meant to imply RTT must be available wherever there is real-time bidirectional voice communication? For example, in a video call, the chat feature may be widely preferred so you have the freedom to backspace (ie change your mind about what you want to say) without the characters already being transmitted. A typing indicator alone would solve the issue of all users not knowing someone wanted to contribute via chat. If RTT itself would become required, this would be a heavy lift and the need for RTT over chat should be research based. If this is not meant to imply RTT is required, it should be reworded.

I believe this is aligned with EN301549
6.2.1.1 RTT communication
Where ICT is in a mode that provides a means for two-way voice communication, the ICT shall provide a means for two-way RTT communication, except where this would require design changes to add input or output hardware to the
ICT.

The goal isn't to change how chat works - but to allow an equivalent to how voice works.
