Add voiceover to a chat story
Voiceover can make a chat story easier to follow while the messages remain visible. Glance Studio offers optional on-device voice generation. It requires a separate model download and a compatible device; start with a short test before building a long narrated project.
Write for speaking as well as reading
A sentence that fits in a bubble may still sound awkward when read aloud. Use short phrases, write numbers the way you want them spoken, and preview names or abbreviations. Listen for pauses that change the meaning of a joke or question.
Keep each character’s delivery consistent. Two distinguishable voices can help, but the visual conversation should still make sense when the viewer watches without audio.
Prepare the device and test one exchange
Complete the required model download before recording a deadline-sensitive project. On-device generation does not mean no initial network access or no storage requirement. Performance depends on the device and the length of the text.
Generate one or two representative lines first. Check the actual language and voice you intend to use. Interface translations do not establish voice quality or language coverage.
Give speech enough room
Avoid revealing the next message while the previous line is still being spoken, unless interruption is part of the scene. Adjust timing after listening rather than relying only on a visual preview.
Lower the music and message sounds until the words remain clear on a small speaker. Adding more sound is not always an improvement; a quiet pause can carry the important moment.
Check the final MP4
Listen to the exported file from beginning to end. Check for clipped words, a cut-off ending, unexpected silence and speech that continues after the video stops. Confirm that the fictional story is understandable without audio as well.
Use voices responsibly and describe staged content honestly. This workflow is for narrating your own script, not for presenting generated speech as a real person’s recording.
