According to one source, it can cost between $30,000 to $300,000 to build an AI voice app like Speechify from the ground up (https://appinventiv.com/blog/cost-to-build-app-like-speechify/). The costs include expenses for research and development, building machine learning models, training data, integration with APIs, and testing. The total depends on the complexity of the features and functionality.

Alternatively, companies can license existing voice AI platforms and APIs like Amazon Polly, Google Cloud Text-to-Speech, Microsoft Azure Cognitive Services, and IBM Watson to reduce development costs. These platforms provide ready-made speech synthesis and natural language processing capabilities that can be integrated into apps. While licensing fees apply, it is more affordable than building custom voice AI from scratch.

Hardware Costs

The hardware required for voice AI systems like microphones, speakers, and processors can add to the overall cost. While basic speech recognition can work with inexpensive microphone setups, high-quality voice interactions require more advanced hardware:

Microphones – Pro-grade condenser microphones provide the best accuracy but cost $100-$500 each. Arrays of multiple mics improve directional hearing.
Speakers – High-fidelity speakers in the $300-$1000 range enable natural sounding voice output.
Processors – Voice recognition and synthesis relies on intensive computations. GPUs or specialized AI chips costing $500+ accelerate performance.

For consumer devices, these components may add $50-$200 or more to the BOM (Bill of Materials) cost. On the high end, advanced microphone arrays and audiophile-quality speakers for commercial applications can cost thousands.

Cloud Hosting Fees

One of the major costs associated with developing and deploying a voice AI system is the fees charged for cloud hosting services like AWS, Google Cloud, Microsoft Azure, etc. These providers offer scalable, on-demand compute and storage resources to host AI models and applications.

According to Google Cloud’s pricing calculator, hosting a small conversational AI application with 1 million queries per month and 30 hours of active speech recognition would cost around $150 per month (Google Cloud). As query volumes and speech recognition usage increases into the hundreds of millions or billions of queries, costs can range from thousands to hundreds of thousands per month.

AWS, Microsoft Azure, and other providers have similar pricing models based on usage of virtual machines, storage, bandwidth, speech services, etc. Overall, cloud fees are a significant but variable ongoing cost, scaling with the success and usage of a voice AI system.

Integration Expenses

Integrating voice AI with existing apps, services, and databases can be a significant cost factor. According to AppInventiv, integrating a chatbot with external databases or APIs can add $5,000 to $15,000 to the overall budget. The more integrations required, the more complex and expensive the project becomes.

Full integration with CRM systems, ERP software, payment gateways, and other backend systems is crucial for many enterprise use cases. This requires custom development work to build APIs and connectors between the voice AI and external platforms. Costs scale rapidly as more integrations get added.

For consumer apps, integration with third-party APIs like weather, maps, audio streaming, or IoT devices is common. Each integration can cost upwards of $5,000 depending on complexity. The total integration costs for a sophisticated voice app could easily exceed $30,000.

Proper integration is key to delivering a robust, functional voice experience. While expensive, integrations enable voice AI to connect with data sources and external services, unlocking the full value of the technology.

Talent Acquisition

Building a capable voice AI team requires hiring talented experts in various domains. Key roles needed include linguists, data scientists, machine learning engineers, conversation designers, and project managers. Compensation for these professionals can be quite high according to market demand.

According to ZipRecruiter, the average hourly wage for AI voice jobs ranges from $5 to $72 per hour, with most jobs paying between $18 to $31 per hour. For specialized roles, salaries are even higher. Research shows AI research scientists can earn between $131,000 to $338,300 at major tech firms like Accenture. Leadership salaries exceed this range.

The need for skilled AI talent has driven up salaries significantly. According to HRDive, the average listed salary for an AI engineer has grown 12% in recent months to $188,000. As demand rises for linguists, conversation designers, and others with voice AI expertise, salaries are likely to increase further.

Maintenance & Support

Once a voice AI system is built and deployed, there are ongoing costs for maintenance and support. This includes any updates, improvements, and bug fixing needed to keep the system running smoothly. According to WebFX, companies spend an average of 15-20% of the initial development costs per year for ongoing maintenance of an AI system.

As the voice AI system is used over time, new issues or desired features will emerge that require engineering work to address. The system may need to be retrained on new data as well to improve accuracy. There are also costs for cloud hosting and fees for support staff to monitor the system and respond to operational issues. Though the maintenance costs vary based on the complexity of the system, companies should budget around $30,000 to $60,000 per year for a typical voice AI application.

Licensing Fees

One significant recurring cost associated with voice AI technology is licensing fees charged by vendors. Major providers like Speechify and Myvox offer licenses and subscriptions for businesses to use their AI voice models and technologies. These licenses can range from $5,000 to $15,000 depending on the features required. Myvox charges $9.99 per month for basic access to their AI voices, while the “Pro” tier for commercial use is $14.99 per month. So licensing fees from major vendors can become a significant recurring expense when deploying voice AI at scale.

Businesses also need to consider any additional licensing costs to ensure accessibility compliance based on regional regulations. Overall, factoring in ongoing vendor licensing fees is crucial when evaluating the total cost of ownership for an AI voice solution.

Return on Investment

While the upfront costs of implementing voice AI can seem high, the potential return on investment makes it worth considering. By automating tasks that previously required human agents, voice AI can generate major cost savings for companies. According to one report, voice AI can reduce customer service costs by up to 30%. The ability for voice AI to handle simple and repetitive tasks like checking account balances, resetting passwords, or providing basic information frees up human agents to focus on more complex issues.
