← Back to BlogHow to Listen to CBZ Comic Books on iPhone
CBZ (Comic Book ZIP) is an archive format that packages comic book pages as sequential images inside a ZIP file. It is the most common digital comic format used outside of major platforms like Marvel Unlimited or ComiXology. Because CBZ files contain images rather than selectable text, getting them read aloud requires OCR technology.
The Challenge
- •CBZ files are essentially ZIP archives of images. There is no selectable text in the file, which means standard text-to-speech tools cannot read them at all.
- •Comic book reader apps on iOS (like Panels or YACReader) are designed for visual reading and do not include OCR or text-to-speech capabilities.
- •Text in comics appears in speech bubbles, captions, and sound effects scattered across the page in non-linear layouts, making automatic text extraction and ordering particularly challenging.
How to Listen with SpeakCove
- 1
Install SpeakCove from the App Store
Download SpeakCove for free. It is one of the few apps that can extract text from image-based formats like CBZ using built-in OCR.
- 2
Open your CBZ file in SpeakCove
Tap the CBZ file from Files, a cloud storage app, or a file manager and choose "Open in SpeakCove." The app recognizes CBZ files directly.

Wait for OCR text extraction
SpeakCove uses Google MLKit OCR to scan each page image and extract readable text. This process is automatic and happens entirely on your device.
- 4
Listen to the extracted text
Press play to hear the extracted dialogue, captions, and narration read aloud. Use sentence highlighting to follow along with the text as it is spoken.

Adjust speed for comic pacing
Comics often have short, punchy dialogue. Adjust the reading speed to match the pace that feels right for the material.
Other Methods
Manually transcribe comic text and use a TTS app

- ✓Works with any TTS app
- ✕Extremely time-consuming — a single comic issue could take hours to transcribe
- ✕Impractical for more than a few pages
- ✕Still requires a separate TTS app to read the transcription
Convert CBZ to PDF, then use a PDF reader
- ✓PDF readers are more common than CBZ readers
- ✓Some PDF TTS apps exist

- ✕Most PDF TTS apps cannot handle image-only pages without OCR
- ✕Adds an unnecessary conversion step
Use Google Lens or Live Text to extract text page by page
- ✓Available on iPhone without extra apps
- ✓Can recognize text in images
- ✕Must be done one page at a time — extremely tedious for a full comic

Frequently Asked Questions
How well does OCR work on comic book pages?
SpeakCove's OCR powered by Google MLKit handles printed text in speech bubbles and captions well. Highly stylized fonts, hand-lettered text, or text overlaid on busy backgrounds may have lower accuracy. Standard digitally-lettered comics work best.
Does SpeakCove read speech bubbles in the correct order?
SpeakCove extracts text from each page and reads it in the order detected by the OCR engine. For most standard comic layouts, this follows a natural reading order, though unconventional page designs may occasionally result in a different sequence.
Can SpeakCove also read CBR (RAR) comic files?
SpeakCove supports the CBZ format. If you have CBR files, you can convert them to CBZ by extracting the RAR archive and re-compressing as ZIP, or by using a free conversion tool.
Is listening to comics useful if I can see the images?
Listening to comics is helpful for accessibility, multitasking, or following along with dialogue while viewing pages. It can also help language learners practice reading and listening simultaneously.
Is there a page limit for CBZ files in SpeakCove?
No. SpeakCove processes CBZ files of any length. Larger files with many high-resolution pages may take slightly longer for OCR to complete, but there is no hard limit.
