Defines the TTS interface. Here, prefix dtk is synonymous with tts.
Add this pattern to the list of repeating patterns that are cleaned up. Optional interactive prefix arg deletes this pattern if previously added. Cleaning up repeated patterns results in emacspeak speaking the pattern followed by a repeat count instead of speaking all the characters making up the pattern. Thus, by adding the repeating pattern ‘.’ (this is already added by default) emacspeak will say ‘‘aw fifteen dot’’ when speaking the string ‘‘...............’’ instead of ‘‘period period period period ’’ (fn &optional DELETE)
Select preferred Cloud TTS server.
Say the available languages.
Select and start an local speech server interactively. Local server lets Emacspeak on a remote host connect back via SSH port forwarding for instance. Argument PROGRAM specifies the speech server program. Port defaults to dtk-local-server-port (fn PROGRAM &optional PROMPT-PORT)
Initialize notification TTS stream.
Shutdown notification TTS stream.
Stop speech on notification stream.
Restore sanity to the Dectalk. Typically used after the Dectalk has been power cycled.
Select a speech server interactively. When called interactively, restarts speech server. Argument PROGRAM specifies the speech server program. Optional arg device sets up environment variable ALSA_DEFAULT to specified device before starting the server. (fn PROGRAM &optional DEVICE)
Set scale FACTOR for speech rate. Speech rate is scaled by this factor when speaking characters. Interactive PREFIX arg means set the global default value, and then set the current local value to the result. (fn FACTOR &optional PREFIX)
Interactively set how text is split in chunks. See the Emacs documentation on syntax tables for details on how characters are classified into various syntactic classes. Argument S specifies the syntax class. (fn S)
Set language according to the argument lang. (fn LANG)
Switch to the next available language
Set speech rate to one of nine predefined levels. Interactive PREFIX arg says to set the rate globally. Formula used is: rate = dtk-speech-rate-base + dtk-speech-rate-step * level. (fn &optional PREFIX)
Set the alias of the preferred language:
For example if alias="en" lang="en_GB",
then the following call:
dtk-set-language("en")
will set "en_GB".
(fn ALIAS LANG)
Switch to the previous available language
Set punctuation mode to MODE. Possible values are ‘some’, ‘all’, or ‘none’. Interactive PREFIX arg means set the global default value, and then set the current local value to the result. (fn MODE &optional PREFIX)
Set punctuation mode to all. Interactive PREFIX arg sets punctuation mode globally. (fn &optional PREFIX)
Set punctuation mode to some. Interactive PREFIX arg sets punctuation mode globally. (fn &optional PREFIX)
Set speaking RATE for the tts. Interactive PREFIX arg means set the global default value, and then set the current local value to the result. (fn RATE &optional PREFIX)
Stop speech now. Optional arg ‘all’ or interactive call silences notification stream as well. (fn &optional ALL)
Toggle allcaps-beep. when set, allcaps words are indicated by a short beep. Interactive PREFIX arg means toggle the global default value, and then set the current local value to the result. Note that allcaps-beep is a very useful thing when programming. However it is irritating to have it on when reading documents.
Toggle capitalization. when set, capitalization is indicated by a short beep. Interactive PREFIX arg means toggle the global default value, and then set the current local value to the result.
Toggle punctuation mode between "some" and "all". Interactive PREFIX arg makes the new setting global. (fn &optional PREFIX)
Toggles state of dtk-quiet. Turning on this switch silences speech. Optional interactive prefix arg causes this setting to become global.
Toggle speak-nonprinting-chars. Switches behavior of how characters with the high bit set are handled. Interactive PREFIX arg means toggle the global default value, and then set the current local value to the result.
Toggle split caps mode. Split caps mode is useful when reading Hungarian notation in program source code. Interactive PREFIX arg means toggle the global default value, and then set the current local value to the result.
Toggle splitting of speech on white space. This affects the internal state of emacspeak that decides if we split text purely by clause boundaries, or also include whitespace. By default, emacspeak sends a clause at a time to the speech device. This produces fluent speech for normal use. However in modes such as ‘shell-mode’ and some programming language modes, clause markers appear infrequently, and this can result in large amounts of text being sent to the speech device at once, making the system unresponsive when asked to stop talking. Splitting on white space makes emacspeak’s stop command responsive. However, when splitting on white space, the speech sounds choppy since the synthesizer is getting a word at a time.
Toggle stripping of octals. Interactive prefix arg means toggle the global default value, and then set the current local value to the result.
Cycle through available ALSA devices. Optional interactive prefix arg restarts current TTS server. (fn &optional RESTART)
Use this to nuke the currently running TTS server and restart it.
Speak version.
List of repeating patterns to clean up. You can use command ‘dtk-add-cleanup-pattern’ bound to C-e d a to add more patterns. Specify patterns that people use to decorate their ASCII files, and cause untold pain to the speech synthesizer.
If more than 3 consecutive occurrences of a specified pattern is found, the TTS engine replaces it with a repeat count.
Set this to your preferred cloud TTS server.
Engine we use for our local TTS server.
*Option that specifies handling of non-printing chars. Non nil value means non printing characters should be spoken as their octal value. Set this to t to avoid a dectalk bug that makes the speech box die if it seems some accented characters in certain contexts.
*Value of lowest tolerable speech rate.
*Value of speech rate increment. This determines step size used when setting speech rate via command ‘dtk-set-predefined-speech-rate’. Formula used is dtk-speech-rate-base + dtk-speech-rate-step*level.
Allow tones to be turned off.
