You can do some customization in iOS 26 with the 16 Pro, which is what I have.
Setting Siri Voice 4 as a VoiceOver voice, you have these extra settings:

Siri Voice 4
Rate

Pitch
Speech Volume
Voice Presets
Default
Even Inflection
Faster Pace
Even Inflection & Faster Pace

Voice presets change the overall speaking style of a voice. They can be further customized with specific voice settings.

It is not the processor of older phones which is the issue, but the amount of RAM. There are 2 new Apple Intelligence features in iOS 27 which require on-device processing and that is only possible with iPhones which have 12 Gb of RAM, here is a quick reply/summary about this:

 

As of iOS 27, Apple has only identified two features that specifically require the new 12 GB RAM on-device Apple Intelligence model:

1. Expressive Siri Voices

Ability to customize Siri's voice with different levels of expressiveness and speaking pace.

 

2. Enhanced Dictation

A significantly more accurate speech-to-text dictation system powered by Apple's most advanced on-device AI model.

 

Which iPhones support these features?

Currently, only iPhones with 12 GB of RAM can run Apple's most advanced on-device AI model:

iPhone 17 Pro

iPhone 17 Pro Max

iPhone Air

 

All other Apple Intelligence-compatible iPhones, including the iPhone 15 Pro, 15 Pro Max, iPhone 16 lineup, and base iPhone 17, can still use the standard Apple Intelligence and Siri AI features, but not these two advanced on-device features.

 

Important distinction

Having an iPhone that supports Apple Intelligence does not automatically mean it supports Apple's most powerful on-device AI model. iOS 27 introduces a new hardware tier based on memory, with 12 GB RAM being the requirement for the top-tier AI capabilities.

 

For me this means I’ll have to see if it will warrant an upgrade from my iPhone 16 Pro which will be 2 years old this fall to an iPhone 18 or 18 Pro. I use dictation quite a lot so if this new enhanced dictation experience is really that much better I may have to consider it. I use a Siri voice for Voiceover, but I’m not so sure if the ability to customize that voice would be such a big deal.

IN this article, there is the statement:

Apple is also updating Siri’s voice to make it sound more natural, with settings for pace and expressiveness. However, that voice customisation feature will only work on iPhone 17 Pro, iPhone Air, or newer models.

 

I then asked Microsoft Copilot:

Copilot said: As of Apple's announced Siri AI rollout, most new Siri AI features are available on iPhone 15 Pro and newer, not just the iPhone 17 Pro.

However, two Siri-related features are currently exclusive to devices with Apple's most advanced on-device AI model, including the iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air. Citation: macrumors plus 1 more Those exclusive features are: Customizable Siri voice expressiveness and speaking pace.

 

So, not all iPhones that can run iOS 27 will have all Siri 2 features.  Beyond this, I don't think anyone knows until Apple officially releases iOS 27 in September.

I ran across this article today and thought maybe others would be interested.  I have not installed the beta so have nothing of substance to add.  The final item in this article mentions some about  VO and Accessibility.

Every iOS 27 feature coming to compatible Apple products

Rebekah Jordan

iOS 27 is coming to compatible iPhones this September, bringing huge upgrades to Siri, AI integrations and more.

The software was revealed during Apple’s WWDC event in June and is currently being tested by developers ahead of a wider release later this year.

Here's everything you can expect in iOS 27:

Siri is getting a major AI upgrade

Siri is getting one of its biggest updates yet in iOS 27, with Apple turning the assistant into something closer to a proper AI companion.

Instead of only handling short commands, Siri 2.0 is designed to understand more natural questions, pick up on personal context and respond based on what users are doing across their device.

It will also be able to pull in up-to-date information from the web and take actions inside apps. That means users could ask Siri to edit a recently sent message, add a song to a playlist, or create a reminder without having to tap through multiple menus. A new Siri app will also give users a place to return to old conversations, pin important chats and continue them across devices through iCloud.

Apple is also updating Siri’s voice to make it sound more natural, with settings for pace and expressiveness. However, that voice customisation feature will only work on iPhone 17 Pro, iPhone Air, or newer models.

The Camera app is getting its own Siri mode too, allowing users to point their iPhone at something and ask questions based on what the camera can see.

Apple Intelligence is coming to more apps

iOS 27 will also push Apple Intelligence deeper into everyday apps. In Safari, the tech giant is adding tools that can group open tabs by topic, helping users find related pages more easily. The browser will also be able to watch webpages for updates, such as restocks or price changes, through a new Notify Me feature.

Another Safari tool, Describe an Extension, will let users create customised browser extensions by explaining what they want the extension to do.

Meanwhile, in Photos, Spatial Reframing will help improve an image's composition after it has been taken, while Extend can fill in missing edges when users straighten a photo or change its shape. Clean Up is also being improved to remove more distracting objects from images.

Image Playground will offer options to edit pictures using instructions or by selecting parts of an image to move or resize. Apple says AI-generated images will carry a SynthID watermark.

Messages and Mail will offer smarter replies that reflect the user’s writing style, while Messages can suggest actions based on the discussion, such as setting a reminder or finding a relevant photo. Users will also be notified by Apple Intelligence to update their passwords in the dedicated app if they enter weak, duplicated or compromised passwords.

iPhone performance is being improved

Not every iOS 27 change is about AI. Apple says the update also includes a wider performance push aimed at making iPhones feel quicker and smoother. Apps are expected to open faster, while transfers through AirDrop and external drives should also be quicker. Photos should import into libraries more rapidly too.

Apple says it has improved networking, display performance, processing efficiency and wireless connectivity across the system. For instance, Search is being upgraded with a stronger device-wide index, which should make it easier to find information across apps, files and settings.

There are a few app-specific updates as well. Maps is getting sharper Flyover visuals with better detail for buildings and trees, while Podcasts will make it easier to move between watching and listening to video episodes.

Parental controls and accessibility are changing too

Apple is also using iOS 27 to expand its child safety and parental control features.

One of the bigger changes is the expansion of Ask to Buy from apps to websites. If a child tries to visit a new website, they will need permission first, and parents can approve or reject the request through Messages. Screen Time is being redesigned to give parents a clearer view of average usage and the apps being used most often.

Parents will also be able to set Time Allowances across apps in iOS 27 (dikushin/Getty)

Parents will also be able to set Time Allowances across categories such as games, entertainment and social media. Apple says the suggested limits will take a child’s age into account, along with advice from clinical experts.

Separately, new scheduling tools will allow or block certain apps at different times of day or on specific days of the week.

Communication Safety is being expanded too. As well as warnings around nudity in Messages, FaceTime and other apps, Apple says the system will also step in before children view violent or graphic images and videos.

Meanwhile in Accessibility, VoiceOver will offer richer image descriptions, Live Recognition will let users ask questions about their surroundings, and Voice Control will allow people to describe onscreen buttons instead of remembering exact labels.

Finally, Accessibility Reader will also support more complex material, with added summaries and translation.
