Hey Stefan,
You’re welcome 
For some inspiration, the quotes used for the static images include the following.
For the carousel format (group of 3 pictures together),
- "Voice technology is powering more tools than more ever before,
- “Today’s voice-enabled devices don’t understand many of the world’s languages, accents and speech patterns”
- “Your Voice can make a difference”
Also here is an example of an image from the campaign.
Feel free to make this your own, so it feels authentic to you and why you contribute to Common Voice.
If you have any questions, feel free to reach out.
