}
}

response = requests.post('https://api.elevenlabs.io/v1/text-to-speech/"your voice id"', headers=headers, json=json_data)
response.raise_for_status()
except requests.exceptions.HTTPError as errh:
print ("HTTP Error:", errh)
except requests.exceptions.ConnectionError as errc:
print ("Error Connecting:", errc)
except requests.exceptions.Timeout as errt:
print ("Timeout Error:", errt)
except requests.exceptions.RequestException as err:
print ("Something went wrong", err)
if response.status_code == 200:
try:
with open('script_audio.mp3', 'wb') as f:
f.write(response.content)
except IOError as e:
print(f"Error writing file: {e}")
else:
print(f"Request failed with status code: {response.status_code}")The provided code appears to be a Python script that reads data from a CSV file, retrieves a prompt from the DataFrame, and sends a text-to-speech request to the Eleven Labs API. It saves the response audio as an MP3 file.
Here’s a breakdown of the code:
read_from_csv(file_path): This function reads data from a CSV file located at the specifiedfile_pathusing pandas'read_csvfunction. It returns the DataFrame containing the data read from the file.- Reading from CSV: The code calls the
read_from_csvfunction with the file name'youtube_content.csv'and assigns the returned DataFrame toread_df. It then prints the DataFrame. - Setting up API request: The code retrieves the prompt from the
'Script'column of the DataFrame and assigns it to thepromptvariable. It sets the headers required for the API request and prepares the JSON payload with the prompt text, model ID, and voice settings. - Sending the API request: The code sends a POST request to the Eleven Labs API using the
requests.postfunction. It includes the API endpoint URL, headers, and JSON payload. The response is stored in theresponsevariable. - Handling the API response: The code checks the response status code. If it is 200 (indicating a successful request), it opens a file named
'script_audio.mp3'in write-binary mode and writes the response content (audio) to the file. If there are any errors during the file write operation, an error message is printed. - Handling request failures: If the response status code is not 200, an error message is printed with the corresponding status code.
Please note that you need to replace "Eleven Lab token" in ELEVENLABS_API_KEY with your actual API key. Additionally, replace "your voice id" in the API endpoint URL with the desired voice ID or model ID for the text-to-speech conversion.
Make sure you have the required libraries (requests, pandas) installed before running the script.
To understand how Eleven Labs API can be utilized for voiceover generation, let’s explore a basic implementation scenario.
3.1 Retrieving Data from CSV Files
The process starts by retrieving the necessary data from a CSV file. The Python script provided in the prompt demonstrates a function called read_from_csv that reads data from a specified CSV file path using the pandas library.
3.2 Preparing the Prompt
Once the data is retrieved, the script extracts the desired prompt from the DataFrame. This prompt serves as the input for the voiceover generation process. It could be a script, narration, or any text that needs to be converted into a voiceover.
3.3 Sending the API Request
After obtaining the prompt, the script constructs an API request by specifying the required headers and JSON payload. The headers contain necessary information, including the API key, and the JSON payload consists of the prompt text, model ID, and voice settings.
3.4 Handling the API Response
The script sends the API request to the Eleven Labs API endpoint and handles the response accordingly. If the request is successful (status code 200), the generated audio content is saved as an MP3 file. In case of any errors or failures, appropriate error messages are displayed.
