From version 2.36, Jutoh provides a new set of functionality for marking up your documents for better text-to-speech quality.
This page describes the new functionality and provides a link to a zip file of documents generated using the new features.
The screenshot below shows the new Speech palette through which you can add markup and preview speech. Click it for a larger image.
Speech markup lets you improve pronunciations, add emphasis, increase pauses between paragraphs, switch voices, and more.
Jutoh generates SSML, SAPI or Apple Speech Manager code and also adds its own enhancements such as picture and table descriptions
where provided by the user. Using styles, some markup such as pauses after headings can be achieved globally without needing to
edit each occurrence.
The following screenshot from the Jutoh editor shows the use of speech markup to add emotion to a sentence,
and conditional formatting to help orient the reader listening to the audio version.
A single Jutoh project can generate MP3, Epub 2, Epub 3, Kindle, OpenDocument (for PDF creation or importing
into a word processor), and HTML by selecting a configuration and pressing Compile.
To aid accessibility further, it's straightforward to create a configuration for large print by defining a point size increment.
The speech sample adds 2pt to all fonts in the 'Large Print OpenDocument' configuration.
The Speech Archive
Jutoh introduces a new file type - the Speech Archive, with extension .sparch. The purpose of this file
is to allow distribution of documents marked up for higher-quality speech, that can be used to generate
speech MP3 files. A recipient of this file can open a .sparch file in a registered or unregistered version of Jutoh,
and generate MP3 files after adjusting various settings such as voice, volume and speed.
Most voices are licensed for personal use, and not for distribution of the resulting audio files, and the speech archive
solves that problem, assuming the recipient has a Windows, Linux or Mac computer.
The speech archive is also a fraction of the size of a set of MP3 files, so it's easy to send as email.
The screenshot on the right shows the result of opening a speech archive file using Jutoh's File | Open command.
It shows some basic information about the book, and has controls for playing or previewing the currently
selected chapter, as well as generating MP3 files in the background.
The Speech Markup Demo
To demonstrate speech markup features, Jutoh comes with a sample project called Patient Advice Speech Sample.jutoh.
It's a short mock-up of an information leaflet, and you can download the output from the sample below. We are grateful to
CereProc for giving us permission to use their Scottish 'Heather' voice for the
MP3 files provided (and also for providing advice on optimising Jutoh for CereVoice).
This zip file contains output of the patient advice speech sample document in various formats: MP3, Epub, Kindle,
PDF and Speech Archive (.sparch). The .sparch file allows you to compile a speech version of the document
without needing the original Jutoh project; you can open it from the Jutoh demo using the menu command File | Open.
