Should I use cloud text-to-speech or build it myself?

Usually, use cloud text-to-speech unless you have a strong reason not to.

Use cloud TTS if you want:

• Fast setup and low engineering effort
• High-quality voices without ML expertise
• Scalability and reliability
• Features like SSML, voice selection, language support, and pronunciation control
• Predictable maintenance handled by a vendor

Build it yourself only if you need:

• Very specific voice behavior or custom branded voices
• Strict privacy / on-prem requirements
• Very high volume where vendor costs become too expensive
• Offline operation
• Deep control over latency, models, and tuning

A good rule of thumb

• If this is a product feature you want live soon: cloud TTS
• If TTS is core to your business and you have ML infra talent: consider building or hybrid
• If you’re unsure: start with cloud, then reevaluate after usage data

Typical tradeoff

• Cloud: cheaper to start, more expensive at scale
• Build yourself: expensive to start, potentially cheaper at scale, but much more complex

Practical recommendation

Start with a cloud provider, measure:

• monthly character volume
• latency
• voice quality requirements
• per-minute or per-character cost
• customization needs

Then decide whether to stay, optimize, or migrate.

If you want, I can help you choose based on your specific case: startup app, enterprise product, offline device, or high-volume platform.
