espeak speech synthesizer warning messages

[jbeale]

I installed the 'espeak' text-to-speech synthesizer which works to generate (mostly) recognizable speech. But each time I try it I get a long list of warning messages from ALSA lib and others, even though it does work. Is this normal, or do I have some mis-configuration?

I have the same problem. I have been searching for an answer but I can’t find anything yet.

Is this normal or am I missing something?

Can anyone suggest anywhere to look to find an answer?

This is the error I get

This is a bit of a shot in the dark, since my Pi is not available, but I solved a similar(?) problem by editing /usr/share/alsa/alsa.conf and changing the following line (comment-out the first, add the second):

Code: Select all

#pcm.front cards.pcm.front
pcm.front cards.pcm.default

Possibly followed by

Code: Select all

sudo alsa reload

Gotta admit though, I don't (and probably never will) "get" ALSA

I've had that in my alsa.conf for months and it doesn't make any difference to the stupid and meaningless stream of messages.

The easiest way to suppress that collection of meaningless stuff is 'espeak "Hello" 2>/dev/null'

Or forget espeak and try this (which needs an Internet connection to work)

Code: Select all

#!/bin/bash
say() { local IFS=+;/usr/bin/mplayer -ao alsa -really-quiet -noconsolecontrols "http://translate.google.com/translate_tts?tl=en&q=$*"; }
say $*

Well, it does decrease it by one

Thanks for the feedback.
I’ve been looking through different forums, but can’t find an answer.
I am having a go at building an RPi robot like the one in issue 132 of Linux User.
So I think I’ll stay with eSpeak as it won’t always have a network connection, and use the “2>/dev/null”.

Thanks again
