Building high-quality speech recognition software for your businesses has never been easier. But one needs the right infrastructure to make the most out of AI transcription at an enterprise scale.
Given the increasing commodification of automatic speech recognition models and APIs, companies today are presented with numerous options on how to build and deploy their AI-powered systems and apps.
Network architecture is the foundation of one's operational efficiency, security, and cost optimization. Companies that want to integrate Speech AI into their tech stack need to decide where they want the underlying network infrastructure to be located, and who they want to own it, while taking into account the specific requirements associated with speech recognition tech.
In this blog, we give you a quick overview of key alternatives - cloud, on-premise and air gap - to help you take an informed decision on which kind of environment is best suited for your needs given your use case and security needs. Bear in mind that Gladia provides all types of hosting for speech-to-text to power enterprise applications. To learn more, contact us directly about the enterprise plan.
Speech recognition, also known as speech-to-text, software may present unique challenges for businesses, demanding specialized considerations beyond traditional hosting and deployment needs. These include the immense processing power and speed required for real-time transcription, bandwidth considerations for handling large audio datasets, and the need for scalable storage solutions. Let's examine some of these in more detail.
Real-time, or live, transcription is an indispensable feature found in voice-based apps like chatbots, media platforms with live captions, and more. As explained in our deep dive on the topic, real-time transcription requires substantial processing power to convert audio signals into accurate output in near real-time. While proximity to the source can be a great advantage for latency in live streaming, top-tier cloud-based API providers can do the job just fine remotely, provided that efficient parallel processing capabilities and a WebSocket support are in place to ensure smooth bidirectional flow of information and fast processing.
Audio datasets can be voluminous, especially in applications dealing with continuous speech or a large number of audio inputs - like customer support and call center operations. Adequate network bandwidth, with suitable compression techniques and optimized data transfer protocols, is essential to transmit large audio files seamlessly, especially in real-time applications.
Storing and managing large volumes of audio data generated by speech-to-text applications requires scalable and efficient storage solutions, too. When deciding on a network environment for audio data, one must anticipate how to accommodate the growing volume of audio data. As explained below, on-premise hosting allows for less flexibility when it comes to scaling in exchanged for increased security.
Speech-to-text applications often deal with sensitive information, raising concerns about data security and privacy. Some use cases and industries require specialized certification and full data sovereignty, with encryption becoming a standard practice whatever the field.
With multi-tenant cloud environments, all users share the same hardware and software, as well as the same instance of the software, provided by a third-party provider that oversees everything from installation to maintenance and software upgrades.
This is the most scalable hosting solution, enabling your company to easily add more users and scale the volume of audio on a pay-as-you-go basis. Regular software updates come as part of the package, with no additional maintenance or upkeep costs. Cloud environments also provide seamless integration with AI and ML services, enhancing the accuracy and efficiency of speech recognition systems.
Like with any third party solution, potential safety hazard in case of a cloud security breach may make this option less suitable for industries with strict privacy and compliance protocols. Also, while flexible tariffs can be very attractive, users should be mindful of processing and storage costs, ensuring they align with the application's usage patterns.
Similar to multi-tenant, except that there's a dedicated cloud infrastructure per client, managed by an external provider, with each user having access to their own instance of the software.
Higher level of security since the virtual network is reserved for a single user.
Better governance.
Higher costs. Also, as with multi-tenant, data security and privacy is dependent on the provider's certifications and capabilities.
On-premise environments, also known as in-house hosting, refers to the deployment of computing resources within an organization's physical location. This includes servers, storage, and networking equipment that is owned and maintained by the organization. Licensed software is hosted on client-controlled data centers, i.e. an exclusive physical and virtual network. The environment tends to be managed by the company’s IT department or, less commonly, a third-party provider.
Data sovereignty, i.e. the user retains full control over what happens to enterprise data.
Significant upfront deployment costs and CAPEX. The uptime can also be impacted significantly in case of hardware failure since, unlike in the cloud, there’s no safety net to fall back on. Moreover, service-level agreements (SLAs) and commitments need to be managed internally.
Air gap hosting is an extreme form of network security where a computer or network is physically isolated from all third party networks - including the internet.
Isolation from external networks minimizes the risk of unauthorized access, providing optimal level of protection for high security facilities with stringent internal protocols, like government and military institutions.
Lengthy time to recovery in case of a local issue (such as natural disaster or business interruption). If the hardware is down or the software needs an upgrade, physical intervention from a certified provider would still be required. Air-gapped environments come with a high cost of maintenance, with roughly the same high CAPEX as on-premise.
In a nutshell, the further we move from 1 to 4, the higher the level of security – but there’s a price to pay (and not just in $$). Beyond significant deployment and maintenance costs, companies hosting on-premise are restricted to the capacity they’ve committed to initially. In other words, they sacrifice the ability to scale.
While the network latency is likely to be better on-premise than in-cloud, that only holds true if their servers are not saturated with users. Should the initial capacity accounted for be exceeded, there’s a lot less room for scaling than with a pay-as-you-go cloud solution— unless one is ready and able to invest in more hardware to scale.
What’s more, security doesn’t need to be compromized when opting for cloud services. As a user, you have a right to verify that a third-party provider meets all the regulatory and security requirements with the necessary certification and beyond. Add-on features like encryption and anonymization can provide an additional degree of security to duly protect your and your customers’ data when working with an ASR API.

Speech-To-Text
Large Language Models (LLMs) are at the forefront of the boom in artificial intelligence (AI) and they continue to get more advanced. However, LLMs can suffer from performance issues, and produce inaccurate, misleading, or biased information, leading to poor user experience and creating difficulties for product builders.
Speech-To-Text
Over the last few years, Large Language Models (LLMs) have become accessible and transformative tools, powering everything from customer support and content generation to complex, industry-specific applications in healthcare, education, and finance.
Case Studies
In recent years, fuelled by advancements in LLMs, the numbers of AI note-takers has skyrocketed. These apps are increasingly tailored to meet the unique needs of specific user groups, such as doctors, sales teams and project managers.
