Verbose mode.

Show the original text and its most relevant translation, then its phonetic notation (if any), then its alternative translations (if any) or its definition in the dictionary (if it is a word).

Show the most relevant translation or its phonetic notation only.

Dictionary mode.

Show the definition of the original word in the dictionary.

Language identification.

Show the identified language of the original text.

Show original text or not. (default: yes)

Listen to the translation.

You must have at least one of the supported audio players (mplayer, mpv or mpg123) installed to stream from Google Text-to-Speech engine. Otherwise, a local speech synthesizer may be used instead (say on macOS, espeak on Linux or other platforms).

Listen to the original text.

Specify the narrator, and listen to the translation.

Common values for this option are male and female.

Specify the audio player to use, and listen to the translation.

Option -play will try to use mplayer, mpv or mpg123 by default, since these players are known to work for streaming URLs. Not all command-line audio players can work this way. Use this option only when you have your own preference.

This option overrides the setting of environment variable $PLAYER.

Do not listen to the translation.

Do not translate anything when using -speak.

Download the audio to the current directory.

Download the audio to the specified file.

View the translation in a terminal pager (less, more or most).

Specify the terminal pager to use, and view the translation.

This option overrides the setting of environment variable $PAGER.

Do not view the translation in a terminal pager.

Specify the web browser to use.

Start an interactive shell, invoking rlwrap whenever possible (unless -no-rlwrap is specified).

Start the GNU Emacs front-end for an interactive shell.

This option does not need to, and cannot be used along with -I or -no-rlwrap.

Do not invoke rlwrap when starting an interactive shell.

This option is useful when your terminal type is not supported by rlwrap (e.g. emacs).

Specify the input file.

Source text to be translated will be read from the input file, instead of standard input.

Specify the output file.

Translations will be written to the output file, instead of standard output.

Specify your home language (the language you would like to see for displaying prompt messages in the translation).

This option affects only the display in verbose mode (anything other than source language and target language will be displayed in your home language). This option has no effect in brief mode.

This option is optional. When its setting is omitted, English will be used.

This option overrides the setting of environment variables $LC_ALL, $LANG, and $HOST_LANG.

Specify the source language(s) (the language(s) of original text). When specifying two or more language codes, concatenate them by plus sign "+".

This option is optional. When its setting is omitted, the language of original text will be identified automatically (with a possibility of misidentification).

This option overrides the setting of environment variable $SOURCE_LANG.

Specify the target language(s) (the language(s) of translated text). When specifying two or more language codes, concatenate them by plus sign "+".

This option is optional. When its setting is omitted, everything will be translated into English.

This option overrides the setting of environment variables $LC_ALL, $LANG, and $TARGET_LANG.

A simpler, alternative way to specify the source language and target language(s) is to use a shortcut formatted string:

• SOURCE-CODE:TARGET-CODE
• SOURCE-CODE:TARGET-CODE1+TARGET-CODE2+...
• SOURCE-CODE=TARGET-CODE
• SOURCE-CODE=TARGET-CODE1+TARGET-CODE2+...

Delimiter ":" and "=" can be used interchangeably.

Either SOURCE or TARGETS may be omitted, but the delimiter character must be kept.

Treat all arguments as one single sentence.

Do not load any initialization script.

End-of-options.

All arguments after this option are treated as TEXT to be translated.
