Send voice file from Nvidia Orin to horn speaker

[nyanmn]

I have Nvidia Orin and running AI for some detections. Like to send a voice file to horn speakr(AXIS C1310-E Network Horn Speaker) from Orin device. How can I do that? Can I send using curl or need to use SDK?

Answers to your questions will most often come from the community, from developers like yourself. You will, from time to time, find that Axis employees answers some of the questions, but this is not a guarantee. Think of the discussion forum as a complement to other support channels, not a replacement to any of them.

If your question remains unanswered for a period of time, please revisit it to see whether it can be improved by following the guidelines listed in Axis support guidelines.

Hi @nyanmn ,
Check if you can use the FFmpeg library on it and then use VAPIX APIs.

Transmit audio data

Adding a Python snippet for your reference to work with Google TTS

import requests
from requests.auth import HTTPDigestAuth
# Import the required module for text 
# to speech conversion
from gtts import gTTS
  
# This module is imported so that we can 
# play the converted audio
import os
  
# The text that you want to convert to audio
mytext = 'Welcome to Axis Audio!'
  
# Language in which you want to convert
language = 'en'
  
# Passing the text and language to the engine, 
# here we have marked slow=False. Which tells 
# the module that the converted audio should 
# have a high speed
myobj = gTTS(text=mytext, lang=language, slow=False)

url = "http://192.168.50.235/axis-cgi/audio/transmit.cgi"


headers = {
  'Content-Type': 'audio/axis-mulaw-128'
}

response = requests.request("POST", url, headers=headers, data=myobj,verify=False,auth=HTTPDigestAuth('root','pass'))

print(response.text)

Tested and found it not working 😞

Adding a snippet which I tested with AXIS C1310-E Mk II Network Horn Speaker AXIS OS version 11.6.92:

Audio file used (Rename and save as s1.wav):

s1_nename_as_wav.txt

Python code:

import requests
from requests.auth import HTTPDigestAuth


def send_audio_to_axis(file_path, axis_speaker_ip):
    # Generate audio file from text using gTTS
    # Prepare the URL and files
    url = f"http://{axis_speaker_ip}/axis-cgi/audio/transmit.cgi"
    files = {'audio': open(file_path, 'rb')}
    headers = {
                'Content-Type': 'audio/basic'
            }
    # Send the request
    response = requests.post(url,files=files,headers=headers,verify=False,auth=HTTPDigestAuth('root','pass'))

    # Check if the request was successful
    if response.status_code == 200:
        print("Audio transmission successful")
    else:
        print("Failed to transmit audio")

# Example usage
axis_speaker_ip = "195.60.68.14"
audio_file_path = "s1.wav"
send_audio_to_axis(audio_file_path, axis_speaker_ip)
