The link you included was for DirectLine v3, which is the latest version of DirectLine.

However, I believe you got the session.say command from this V3 Doc. Unfortunately, it doesn't have a V4 equivalent.

However, most of the Message types have a speak or ssml property (JS / C#) you can use to send the text that will be spoken.

It works the same way. Instead of using (from the V3 doc):

JS v3

var msg = new builder.Message(session)
    .text('This is the text that will be displayed')
    .speak('This is the text that will be spoken.');
session.send(msg).endDialog();

C# v3

Activity msg = activity.CreateReply("This is the text that will be displayed."); 
reply.Speak = "This is the text that will be spoken.";
reply.InputHint = InputHints.AcceptingInput;
await connector.Conversations.ReplyToActivityAsync(reply);

You'd use:

JS v4

var msg = MessageFactory.text({ text: "This is the text that will be displayed", ssml: "This is the text that will be spoken" });
await context.SendActivity(msg);

C# v4

var msg = MessageFactory.Text(text: "This is the text that will be displayed", ssml: "This is the text that will be spoken");
await context.SendActivity(msg);

The await line might vary, depending on where/how you use it in your bot.

Note that to test speech, there's a few additional steps to set up. You can find references for that here:

And finally, here's a sample bot that uses Cortana and speech. Specifically, you can see how it uses MessageFactory.text here.
