  • Core AI Services
  • Platform and Integration Services

Core AI Services

ASR allows more fluidity in the conversation because users can speak instead of typing a long text to explain an issue. OpenAI’s ‘Whisper’ provides this service, and the market size of speech recognition as a service is set to reach 83 billion USD by 2032.

  • Natural Language Processing (NLP):

    This service is an improvement on speech recognition because this service allows more insight into the context and the tone of speech.  AI voice agents having access to this service can reply better to customer queries and effectively guide them through the troubleshooting process. Brands like Rasa are the market leaders offering this service to businesses.

  • Text-to-Speech (TTS):

    This service helps users to listen to the troubleshooting guidelines provided by a generative AI system rather than read them. Data reveals that TTS can cut research time by up to 75%, making it a sustainable and convenient way to comprehend data. Amazon Polly is a popular service that can convert any piece of text to an audio stream.

FAQs about Service You Should Use for AI Voice Agents in 2025?

1. Why are Core AI services not enough for my voice agents in 2025?

The best way to explain this is by analogy with the dismantled pieces of a bicycle: you know that you have all the required parts to build a perfectly working bicycle, but can you put them together by yourself? Even if you can, doing so might shift your focus away from the important business operations that actually drive profits. It is at this point that businesses collaborate with reliable brands like Atidiv to ensure an impeccable CX for customers without having to intervene in the core processes.

2. Do I need NLP when I already have ASR services?

The answer to this question depends on the level of expertise you would like to have with voice agents in your CX. ASR works fine for basic requirements, but for intricate functions like tone and context recognition, NLP is a must. If you want a total automation of the repetitive CX processes, NLP is a must because it can recognize and delegate complex issues to the human CX for better resolution. 

3. Why are Telephony services still so important, and why should I focus on them?

Telephony, or inbound and outbound call center services, are important components of omnichannel support simply because a significant number of people still prefer calls to chatting. Therefore, you must focus on these services, along with other services like email support and chatbots, so that customers with a diverse range of requirements can reach out to you 24/7.
