grpcio skips 1.79.x (releases jump 1.78.0 → 1.80.0). Environments combining tts-api with livekit-agents>=1.5.1 fail at runtime with grpcio 1.78.x because livekit's transitive gRPC stubs require >=1.80.0. No stub regeneration needed: the generated stubs (GRPC_GENERATED_VERSION ='1.70.0') are forward-compatible with grpcio 1.80.0. Bumps version to 3.2.2.

grpcio skips 1.79.x (1.78.0 → 1.80.0). Environments using tts-client-python alongside livekit-agents>=1.5.1 fail at runtime with grpcio 1.78.x. Aligns with tts-api-python v3.2.2 which carries the same fix upstream (techmo-pl/tts-api-python#5).

Summary
grpciolower bound from>=1.70.0to>=1.80.0for Python 3.9+ inpyproject.toml3.2.1+1→3.2.2Background
grpcioskips the1.79.xseries entirely (releases jump1.78.0→1.80.0). Whentts-apiis used alongsidelivekit-agents>=1.5.1, livekit's transitive gRPC stubs requiregrpcio>=1.80.0at runtime. With the old lower bound (>=1.70.0), pip could resolvegrpcio==1.78.0— satisfying the declared constraint but breaking at runtime.The generated stubs (
GRPC_GENERATED_VERSION='1.70.0') are forward-compatible with grpcio 1.80.0, so no stub regeneration is required.Test plan
