Using ev3dev and python to speak a few words in english in english is very easy:<\/p>\n\n\n

\nfrom ev3dev2.sound import Sound\nsound = Sound()\nsound.speak('Good morning')\n<\/pre><\/div>\n\n\n
Making it speak portuguese words is also easy:<\/p>\n\n\n
\nfrom ev3dev2.sound import Sound\nsound = Sound()\nsound.speak('Bom dia', espeak_opts='-v pt')\n<\/pre><\/div>\n\n\n
not a great pronounce but still understandable.<\/p>\n\n\n\n
Problems started when trying to speak sentences written with portuguese characters like “Ol\u00e1” (“Hello”)<\/p>\n\n\n
\nsound.speak('Ol\u00e1', espeak_opts='-v pt')\n<\/pre><\/div>\n\n\n
it generates an error similar to this:<\/p>\n\n\n\n
UnicodeEncodeError: 'ascii' codec can't encode character u'\\xa0' in position 20: ordinal not in range(128)<\/pre>\n\n\n\n
my ev3dev installation wasn’t configured to understand non-ASCII characters so a quick setting at the command line corrected this:<\/p>\n\n\n\n
$ export LC_ALL=\"en_US.UTF-8\"\n$ export LC_CTYPE=\"en_US.UTF-8\"<\/pre>\n\n\n\n
Now I wanted to speak the current date, like ‘Today is Friday 25 December” so I found ‘datetime’<\/p>\n\n\n
\nfrom datetime import datetime as dt\nimport datetime\n\ntoday = dt.today()\nspeech = today.strftime("%A") + ' ' + today.strftime("%-d") + ' ' + today.strftime("%B")\nsound.speak('Today is ' + speech)\n<\/pre><\/div>\n\n\n
Great. At least in english. But how to do it in portuguese (i.e. ‘Hoje \u00e9 Sexta 25 Dezembro”)? How to make today.strftime(“%A) return “Sexta” instead of “Friday”?
The trick is using ‘locale’:<\/p>\n\n\n
\nfrom datetime import datetime as dt\nimport datetime\nimport locale\n\nlocale.setlocale(locale.LC_TIME, "pt_PT") \ntoday = dt.today()\nspeech = today.strftime("%A") + ' ' + today.strftime("%-d") + ' ' + today.strftime("%B")\nsound.speak('Today is ' + speech)\n<\/pre><\/div>\n\n\n
And now another error:<\/p>\n\n\n\n
locale.Error: unsupported locale setting<\/pre>\n\n\n\n
ev3dev doesn’t have Portuguse locale settings (we can check with ‘locale -a<\/code>‘). So I needed to install them:<\/p>\n\n\n\n
$ sudo dpkg-reconfigure locales<\/pre>\n\n\n\n
