Hi,
gibt es eine Möglichkeit bei der pascom text to speech zu nutzen . bzw. hat das jemand am laufen?
Gruss

Hallo @florian.schermer,
ja, mache ich per AGI.
Der Aufruf:
same => n,agi(googletts.agi,"das geht ja toll mit der pascom",de)
das AGI:
#!/usr/bin/env perl
#
# AGI script that uses Google's translate text to speech engine.
#
# Copyright (C) 2011 - 2015, Lefteris Zafiris <zaf@fastmail.com>

#
# -----
# Usage
# -----
# agi(googletts.agi,"text",[language],[intkey],[speed]): This will invoke the Google TTS
# engine, render the text string to speech and play it back to the user.
# If 'intkey' is set the script will wait for user input. Any given interrupt keys will
# cause the playback to immediately terminate and the dialplan to proceed to the
# matching extension (this is mainly for use in IVR, see README for examples).
# If 'speed' is set the speech rate is altered by that factor (defaults to 1.2).
#
# The script contacts google's TTS service in order to get the voice data
# which then stores in a local cache (by default /tmp/) for future use.
#
# Parameters like default language, sample rate, caching and cache dir
# can be set up by altering the following variables:
# Default langeuage: $lang
# Sample rate: $samplerate
# Speed factor: $speed
# Chace: $usecache
# Chache directory: $cachedir
# SoX Version: $sox_ver

Ich würde das Thema gerne neu aufgreifen und die googletts.agi wieder nutzen. Bis zu 17er hat das auch prima funktioniert. Wo muss denn das Skript bei einer 18er Version liegen, damit das wieder funktioniert. Das Log meint, etc/asterisk/agi/googletts.agi fehlt, doch in welchem Container wird das erwartet?
Vielleicht gibt es da ja mittlerweile auch bessere / einfachere Methoden?!
Gruß
Michael
Hab es gefunden, gehört in den Instanz-Container der Asterisk. Also soweit so gut. Aber etwas holprig klingt das immer noch. Ist bei Pascom direkt schon angenehmer zu hören. Vielleicht wird da ja ein neueres AGI-Skript verwendet?
Hallo @noses
Wir verwenden kein AGI sondern haben das direkt mit dem Google Wavenet erzeugt. Das ist eine kommerzielle, wenn auch recht günstige, API von Google.
Ja, das hatte ich schon gesehen bei Google. Ist halt die Frage, wie ich das in die Pascom eingebunden bekomme. Gibt es da etwas, was ihr schon teilen könntet?
Gruß
Michael
Hallo @noses
Noch nicht. Wir haben die prompts einfach per Google API erstellt und dann in die pascom hochgeladen. Wir haben eine Integration des Google WaveNet in pascom auf der Roadmap - allerdings noch ohne konkrete Version oder Datum.
Hallo,
wir nutzen seid einiger Zeit ein Shellscript um mp3 Dateien über die Google Api zu erzeugen.

Hi Flo,
magst das dann auch herzeigen?

Hallo , das Shellscript würde mich auch sehr interessieren 
Gruß Jörg
Da man auf der pascom scheinbar auch PHP verwenden kann, kommt auch folgendes in Frage:
Aber schade, dass das nicht direkt integriert ist.
Gibt es da schon was neues?
