$text = \"Bon dia, com esteu?\";\n$lang = \"ca\";\n\nfitxer = generarTTS($lang, $text);<\/pre>\n\n\n\n
i que produeixi autom\u00e0ticament:<\/p>\n\n\n\n
sortida_ca.mp3\nsortida_es.mp3\nsortida_en.mp3<\/pre>\n\n\n\n
o b\u00e9 .wav<\/code>.<\/p>\n\n\n\n
Com que tu ja tens gTTS al Synology<\/strong>, una opci\u00f3 molt pr\u00e0ctica \u00e9s que PHP cridi un petit script Python<\/strong> que faci la conversi\u00f3. Aix\u00ed PHP nom\u00e9s s’encarrega de passar $lang<\/code> i $text<\/code>.<\/p>\n\n\n\n
Per exemple, l’arquitectura seria:<\/p>\n\n\n\n
PHP\n \u2502\n \u2502 $lang + $text\n \u25bc\nPython \/ gTTS\n \u2502\n \u251c\u2500\u2500 ca \u2192 sortida_ca.mp3\n \u251c\u2500\u2500 es \u2192 sortida_es.mp3\n \u2514\u2500\u2500 en \u2192 sortida_en.mp3<\/pre>\n\n\n\n
Tamb\u00e9 podem fer que la mateixa funci\u00f3 decideixi autom\u00e0ticament el nom:<\/p>\n\n\n\n
generarTTS(\"ca\", \"Bon dia\");\n\u2192 sortida_ca.mp3\n\ngenerarTTS(\"es\", \"Buenos d\u00edas\");\n\u2192 sortida_es.mp3\n\ngenerarTTS(\"en\", \"Good morning\");\n\u2192 sortida_en.mp3<\/pre>\n\n\n\n
I encara millor:<\/strong> podem fer que la funci\u00f3 PHP retorni el nom\/ruta del fitxer generat<\/strong>, cosa que encaixa molt b\u00e9 amb el teu Flask\/Python actual i amb la reproducci\u00f3 autom\u00e0tica al navegador.<\/p>\n\n\n\n
Si vols, et puc preparar ara mateix la funci\u00f3 PHP completa generarTTS($lang, $text)<\/code><\/strong>, preparada per al teu Synology, incloent-hi ca<\/code>, es<\/code> i en<\/code> i controlant errors.<\/p>\n\n\n\n
\n\n\n\n
\n\n\n\n
S\u00ed. Aqu\u00ed veig un punt molt probable de problema de codificaci\u00f3<\/strong>: estem passant el text catal\u00e0 directament com a argument de la shell:<\/p>\n\n\n\n
escapeshellarg($text)<\/pre>\n\n\n\n
Amb textos com:<\/p>\n\n\n\n
Bon dia, s\u00f3c l'Ona. Qu\u00e8 tal?<\/pre>\n\n\n\n
els car\u00e0cters \u00f3<\/code>, \u00e8<\/code>, \u00e7<\/code>, \u00e0<\/code>, etc. poden donar problemes segons la configuraci\u00f3 de locale<\/code> de PHP\/Apache.<\/p>\n\n\n\n
La manera m\u00e9s segura \u00e9s no passar mai el text UTF-8 directament per la shell<\/strong>. El codifiquem en Base64 a PHP i Python el recupera. Aix\u00ed \u00f3<\/code>, \u00e8<\/code>, \u00e7<\/code>, emojis, ap\u00f2strofs, cometes, etc. arriben intactes.<\/p>\n\n\n\n
