WebsocketError with ErrorCode 429

[kxxt]

The free trial API is heavily rate limited by Microsoft.

If you are constantly hitting this with an error code 429, please consider registering an Azure account and use aspeak with an azure subscription key. (There is a free tier)

Or you can try to use the edge tts endpoint which comes with fewer features(You need at least aspeak v4.2.0). You can figure out what options are needed by looking at edge-tts's code:

• https://github.com/rany2/edge-tts/blob/58307ded2632fc2bd3a89779a67d5a2e3f6af798/src/edge_tts/communicate.py#L313-L321
• https://github.com/rany2/edge-tts/blob/58307ded2632fc2bd3a89779a67d5a2e3f6af798/src/edge_tts/communicate.py#L352

Hi, I registered an Azure account and used aspeak with my subscription key. But I constantly hit some similar errors when I used my configuration file:

Error:
0: Websocket error
1: HTTP error: 429 Too Many Requests

Location:
src\main.rs:79

Backtrace omitted. Run with RUST_BACKTRACE=1 environment variable to display it.
Run with RUST_BACKTRACE=full to include source snippets.

Could you help me?

Hi, I registered an Azure account and used aspeak with my subscription key. But I constantly hit some similar errors when I used my configuration file:

Hi, @babykidp. What's the command you used and the relevant config entries(region and endpoint)?

You should use an official API endpoint instead of the default trial endpoint. For example, for eastus region, you can run aspeak -r eastus -k YOUR_KEY text "Hello World".

[babykidp]

I use the command:
aspeak --profile MY_PROFILE text "Hello"

My profile looks like this:

[auth]
endpoint = "https://eastasia.api.cognitive.microsoft.com/sts/v1.0/issuetoken"
region = "eastasia"

It‘s OK when I only run aspeak -r eastasia -k MY_KEY text "Hello World".

[babykidp]

And I met another error about endpoint:

Error:
0: TOML parse error at line 19, column 12
0: |

When my profile is set up without endpoint, I met some other error:
[auth]
region = "eastasia"

Error:
0: Websocket error
1: HTTP error: 200 OK

[auth]
endpoint = "https://eastasia.api.cognitive.microsoft.com/sts/v1.0/issuetoken"
region = "eastasia"

The endpoint url should be something like "wss://eastus.api.speech.microsoft.com/cognitiveservices/websocket/v1". You don't need to specify endpoint url if you have specified region. The endpoint url setting will be used instead of the region setting if you specified both.

And I met another error about endpoint:

This should be a bug of aspeak. I will fix it.

My Azure Keys and Endpoint page shows the endpoint as: https://eastasia.api.cognitive.microsoft.com/sts/v1.0/issuetoken. That's different from the default endpoint.

The endpoint url in aspeak config is not the issuetoken API url. A list of TTS endpoints can be found at https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/rest-text-to-speech?tabs=streaming#prebuilt-neural-voices . And you need to change https:// to wss:// as aspeak is using the websocket API.

There is a bug that caused the endpoint/region settings in profile ineffective. I will fix it soon.

[babykidp]

I see, thank you!

[kxxt]

@babykidp The region setting should now be effective with aspeak v4.3.1. Thanks for your error report.

[babykidp]

You're welcome. The new version works well now.

I found some new error. No matter whether I set the region or not, once I set the endpoint as your guide, a new error occurs. The new version works well when I only specify region.

[auth]
endpoint = "wss://eastasia.tts.speech.microsoft.com/cognitiveservices/v1"
region = "eastasia"

Ah, it should be wss://eastasia.tts.speech.microsoft.com/cognitiveservices/websocket/v1. There is a subtle difference between the REST API endpoint and the websocket API endpoint.

[babykidp]

Thank you for your help. I missed "websocket".

The trial endpoint has been removed in v5.0.
