Can't get/find "speak" or "voice" boxes/options

Hi, no matter what I do with the settings in my project I can't seem to get an option to have a voice or speak box become available. I am attempting to build, essentially, a "sound board" type of application for a sales use case. It will be a "decision tree" format where I can choose between text to speech (I have an elevenlabs integration/account) and just playing a pre-recorded audio clip. I figured out how to make the text to speech work fine but I don't have any options/choices for "speak/audio" boxes and I only have "message" options (not "voice") when creating a block. PLEASE advise.

Hey there! – the old “Speak / Audio” blocks were rolled into the single Message step in the current Voiceflow builder, so you won’t see a separate “voice” block anymore. How to do what you need: 1. TTS with ElevenLabs • Open Project ▸ Settings ▸ Integrations ▸ ElevenLabs and drop in your API key. • Any Message step that contains plain text will now be rendered with your ElevenLabs voice when you test on a voice-enabled channel (web-chat with audio on, telephony, VAPI, etc.). 2. Play a pre-recorded clip instead of TTS • In the same Message step paste SSML that points to the file you want to play, e.g.

      <speak>
        <audio src="https://mysite.com/audio/greeting.mp3" />
      </speak>

      <speak>
        <audio src="https://mysite.com/audio/greeting.mp3" />
      </speak>

• If you also want TTS plus a clip in the same output you can mix them, e.g.

      <speak>
        Welcome! <break time="300ms"/>
        <audio src="https://mysite.com/audio/deal_bell.mp3"/>
      </speak>

      <speak>
        Welcome! <break time="300ms"/>
        <audio src="https://mysite.com/audio/deal_bell.mp3"/>
      </speak>

3. Decision tree / sound-board flow • Build your tree with normal Choice → Message steps. • For a “TTS branch” put plain text in the Message. • For a “Clip branch” put the SSML above. That’s it—no extra blocks required. The Message step decides at runtime whether to synthesize or just stream the audio tag you give it.

Why are these the only integrations I see?

no twilio? should this work: <speak> <audio src="https://www.dropbox.com/scl/fi/whr9ifdqyvdntz03095yl/ElevenLabs_2025-06-20T15_41_10_Sage-Voice-1_jesus_camp.mp3?rlkey=n40qspbxzc4y99b3gyedi9e3u&st=z198xq6s&dl=0" /> </speak>?
