I am new to Larynx, so maybe my question can be answered easily and quickly, but I couldn't find anything to fix it.

Whenever a dot character is encountered, synthesis ends. I don't even need multiple sentences, but if it encounters something like X (feat. Y) it just says X feat. I am using Larynx over opentts in Home Assistant, but this can easily replicated in the GUI as well. So how exactly can I fix this? And maybe for later, how exactly can I synthesize multiple sentences? Thank you very much in advance, the voices are superb!

Hi Michael,

congratulations for your Larynx v1.0 release :partying_face: . Great work, as usual :slightly_smiling_face:.

I've been trying to use Larynx with the new SEPIA v0.24.0 client since it has an option now to use MaryTTS compatible TTS systems directly, but encountered some issues:

• The /voices endpoint is not delivering information in the same format. The MaryTTS API response is: [voice] [language] [gender] [tech=hmm] but Larynx is giving [laguage]/[voice]. Since I'm automatically parsing the string it currently fails to get the right language.
• The /voices endpoint will show all voices including the ones that haven't been downloaded yet.
• The Larynx quality parameter is not accessible.

The last point is not really a MaryTTS compatibility issue, but it would be great to get each voice as 'low, medium, high' variation from the 'voices' endpoint, so the user could actually choose them from the list.

I believe the Larynx MaryTTS endpoints are mostly for Home-Assistant support and I'm not sure how HA is parsing the voices list (maybe it doesn't parse it at all or just uses the whole string), but it would be great to get the original format from the /voices endpoint. Would you be willing to make these changes? :innocent: :grin:

I have a working setup on a recent linux box (with python 3.8). But now I have to use an older computer (python 3.5, pip 8.1.1) and I run into trouble:

 Using cached https://files.pythonhosted.org/packages/f8/4d/a2.../larynx-0.3.1.tar.gz
 Complete output from command python setup.py egg_info:

What are the minimum versions required by larynx at the moment?

Steps to reproduce:

1. Run larynx-server on NixOS with Docker
2. Attempt to download a tts

Did you think about using pavoque-data for German voice? https://github.com/marytts/pavoque-data/releases/tag/v0.2 It has better quality in comparing with thorsten audio dataset. It has restriction for commercial using but as I see you already have a voice with that restriction.

I'm using the docker command mentioned in https://github.com/rhasspy/larynx#docker-installation

However, when I flip the port number in the docker run command, it doesn't work the way I want it to. May I know the right way to host larynx in a different port, if there is one

I'm having trouble setting up the MaryTTS component in Home Assistant to work with Larynx. In particular, there are several parameters that can be defined in yaml. The docs give this example:

tts:
  - platform: marytts
    host: "localhost"
    port: 59125
    codec: "WAVE_FILE"
    voice: "cmu-slt-hsmm"
    language: "en_US"
    effect:
      Volume: "amount:2.0;"

Larynx is up and running and I can generate speech via localhost:59125. I'd like to use a specific voice and quality setting with Home Assistant's TTS. I tried setting the following:

...
    voice: "harvard-glow_tts"
    language: "en_us"
...

But Home Assistant's log shows an error saying that "en_us" is not a valid language ("en_US" is, though).

What are the correct parameters necessary to use a specific voice? And would it be possible to use an effect key to set the voice quality (high, medium, low)?

Thanks @synesthesiam for this excellent tool.

I followed the 'Python installation' method (on Ubuntu 20.10) and added the language de-de via python3 -m gruut de-de download. Before I could use the new language, I had to add a link in ~/.local/lib/python3.8/site-packages/gruut/data/ to ~/.config/gruut/de-de; otherwise the new language was not found.

Impressive program!

Using a bash script, how do I send text to the larynx SERVER?

When using the larynx CLI, there is a 5-15 second startup delay (which I'm trying to eliminate). So I'd like to start a server, then send the text to the server to avoid this startup delay.

Unfortunately, I've failed to find documentation or an example on how to connect to the server using a bash script. I've experimented with the "--daemon" option, and studied the larynx-server example, but failed to find a solution. (Please forgive my inexperience with TTS.)

I'd appreciate an example (or pointer to documentation) showing how to send text to the larynx server using a bash script. Thank you.

Looks like the Github version tag is 1.0 but the code is looking for 1.0.0. The assets exist on Github with 1.0 in the path, but I'm getting this error when trying to download voices from the web interface:

larynx.utils.VoiceDownloadError: Failed to download voice en-us_kathleen-glow_tts from http://github.com/rhasspy/larynx/releases/download/v1.0.0/en-us_kathleen-glow_tts.tar.gz: HTTP Error 404: Not Found

I am getting HTTP 500 returned when I go to http://localhost:5002/openapi/ - The browser page says "Fetch error undefined /openapi/swagger.json"

On the command line, I tried find /usr/local/python3/ -name '*swagger*' and only got results for the swagger_ui package in site-packages.

I hope to gain some understanding about how feasible and useful it is to cache certain (intermediate) outputs. If large parts of phrases are re-used often, couldn't they be cached (perhaps on multiple levels) to improve response time? And if so, the cache could be pre-populated with expected outputs by speaking them all once. For example a program that reads the time of day could have a cache for 'The time is' as well as numbers up to 59. The expected reduction in response time would depend on which parts of the process actually take the most time, which I'm not sure about.

I was really confused for a moment the first time I encountered this. :-)

To reproduce:

1. Run the Larynx server via the latest Docker container.
2. Open the web interface. Paste a phrase like "It was popular in the distant past of the 1700s." and press "Speak".

I'm using larynx==1.1.0

Even when I specified --voices-dir with directory which contains correct voice models, it seems not be used.

python3 -m larynx.server --voices-dir /var/lib/larynx-model/voices

It would be nice to trap the favicon.ico HTTP request and return a simple icon so that the browser does not get a 500 error and the client does not log the error message.
