What is LTI?
LTI is an abbreviation for Learning Tools Interoperability, which is a standard protocol developed by the IMS Global Learning Consortium. It allows services like VoiceThread to integrate with your Haiku environment as single-sign-on tools.
The resulting experience for instructors and students is simple:
- Sign in to your Haiku account.
- Navigate to your course.
- Click on the VoiceThread LTI link.
- Use VoiceThread.
Clicking on a VoiceThread LTI link will authenticate the user, establish an account for him if he didn’t have one already, and enroll him in his course within VoiceThread. No additional work is required from the instructor or student.
LTI Tool Configuration
Before instructors can use VoiceThread, it must be configured globally for your Haiku instance by an administrator.
- Navigate to Domain Control.
- Click the “Applications” tab.
- Click on “LTI Tools” in the menu bar.
- Click “+Add LTI Tool”.
- Name the configuration (for example: “VoiceThread”).
- For Host, enter: https://yourdomain.voicethread.com/ltione/
- Enter your Key and Secret (provided by VoiceThread).
- Check the Privacy box that says “Share names and email addresses with tool”.
- Click “Save”.
- If the tool is disabled, click on “Manage Tool” and select “Enable”.
- If you want to add a VT icon for this tool, click on “Manage Tool” and select “Change icon”. The following icon is formatted for the Haiku display space: https://voicethread.com/resources/vt-logo-3.png

Haiku is currently only certified for LTI 1.0. Gradebook integration requires LTI 1.1 or higher. As soon as Haiku is conformant with LTI 1.1, VoiceThread gradebook integration will be available.

Make sure your web browser accepts third-party cookies.
When you click on a VT link, you see a page titled “VoiceThread Account Verification”.
This means you already had a VoiceThread account under your email address, and the system is now trying to connect that existing account with your Haiku profile. You’ll only need to complete this step once. To proceed through this page:
- Click on the link that says “Set it here” to set a verification password for your account.
- Proceed through the steps to set a password. This will involve receiving an email from VoiceThread.
- Use that password you just set on the verification page.
